| QTI CPR (Core Power Reduction) Regulator |
| |
| CPR regulator device is for QTI RBCPR (RapidBridge CPR) on |
| application processor core. It takes voltage corner level |
| as input and converts it to actual voltage based on the |
| suggestions from factory production process. When CPR is |
| enabled for application processer core, it will suggest |
| scaling the voltage up or down for best performance and |
| power of the core. The scaling based on factory production |
| process is called PVS (Process Voltage Scaling) with efuse |
| bits to indicate what bin (and voltage range) a chip is in. |

| [1]: => the PVS version of the CPU |
| [2]: => the CPR fuse revision |
| [3 - N+2]: => the ring oscillator select value of each fuse corner |
| ordered from lowest to highest |
| Any element in a tuple may use the value 0xffffffff as a wildcard |
| which will match against any fuse parameter value. The first tuple |

| their lists. |
| - qcom,cpr-allowed: Integer values that specifies whether the closed loop CPR is allowed or |

| If the integer value has a value 0 for a particular fuse revision, then it |
| is treated as if the closed loop operation is disabled in the fuse. If the |
| integer value has a value 1 for a particular fuse revision, then the closed |

| for a particular fuse revision, then the closed loop operation is enabled |
| for that fuse revision by default. |

| quotients of each fuse corner. The elements in a tuple are ordered from |

| property is specified, then qcom,cpr-quotient-adjustment must contain the |
| same number of tuples as qcom,cpr-fuse-version-map. These tuples are then |
| mapped one-to-one in the order specified. E.g. if the second |
| qcom,cpr-fuse-version-map tuple matches for a given device, then the quotient |
| adjustments defined in the second qcom,cpr-quotient-adjustment tuple will |
| be applied. If the qcom,cpr-fuse-version-map property is not specified, |
| then qcom,cpr-quotient-adjustment must contain a single tuple which is then |
| applied unconditionally. If this property is specified, then the quotient |
| adjustment values are added to the target quotient values read from fuses |
| before writing them into the CPR GCNT target control registers. |
| This property can be used to add or subtract static voltage margin from the |
| regulator managed by the CPR controller. |
| - qcom,cpr-init-voltage-adjustment: Array of integer tuples of initial voltage adjustments in microvolts to |
| add to the fused initial voltage values of each fuse corner. The elements |
| in a tuple are ordered from lowest voltage corner to highest voltage corner. |
| Each tuple must be of the length defined by qcom,cpr-fuse-corners. If the |
| qcom,cpr-fuse-version-map property is specified, then |
| qcom,cpr-init-voltage-adjustment must contain the same number of tuples as |
| qcom,cpr-fuse-version-map. These tuples are then mapped one-to-one in the |
| order specified. E.g. if the second qcom,cpr-fuse-version-map tuple matches |
| for a given device, then the initial voltage adjustments defined in the |
| second qcom,cpr-init-voltage-adjustment tuple will be applied. If the |
| qcom,cpr-fuse-version-map property is not specified, then |
| qcom,cpr-init-voltage-adjustment must contain a single tuple which is then |
| applied unconditionally. This property can be used to add or subtract |
| static initial voltage margin from the regulator managed by the CPR |
| controller. |
| - qcom,cpr-quot-offset-adjustment: Array of integer tuples of target quotient offset adjustments to add |
| to the fused quotient offsets of each fuse corner. The elements in a tuple |
| are ordered from lowest voltage corner to highest voltage corner. Each tuple |
| must be of length defined by qcom,cpr-fuse-corners. If the qcom,cpr-fuse-version-map |
| property is specified, then qcom,cpr-quot-offset-adjustment must contain the |
| same number of tuples as qcom,cpr-fuse-version-map. These tuples are then |
| mapped one-to-one in the order specified. E.g. if the second |
| qcom,cpr-fuse-version-map tuple matches for a given device, then the quotient |
| offset adjustments defined in the second qcom,cpr-quot-offset-adjustment tuple |
| will be applied. If the qcom,cpr-fuse-version-map property is not specified, |
| then qcom,cpr-quot-offset-adjustment must contain a single tuple which is then |
| applied unconditionally. If this property is specified, then the quotient |
| offset adjustment values are added to the target quotient offset values read |
| from fuses. |
| This property can be used to add or subtract static quotient offset margin from |
| the regulator managed by the CPR controller. |
| - qcom,cpr-clamp-timer-interval: The number of 64 reference clock cycle blocks to delay for whenever |
| the clamp signal, sensor mask registers or sensor bypass registers |
| change. The CPR controller loop is disabled during this delay. |
| Supported values are 0 to 255. If this property is not specified, |
| then a value of 0 is assumed. Note that if this property has a |
| value greater than 0, then software cannot accurately determine the |
| error_steps value that corresponds to a given CPR measurement |
| unless processor power collapsing is disabled. If this property |
| has a value of 0, then the CPR controller loop is not disabled and |
| re-enabled while idle if the clamp signal changes. Instead, it |
| will remain idle until software issues an ACK or NACK command. |
| This ensures that software can read the error_steps value which |
| resulted in the CPR up or down interrupt. Setting this property to |
| a value greater than 0 is useful for resetting the CPR sensors of a |
| processor that uses BHS type voltage switches in order to avoid |
| anomalous CPR up interrupts when exiting from power collapse. |

| The elements in one tuple are: |
| [0]: => the speed bin of the CPU. It may use the value 0xffffffff as a |

| a wildcard to match any PVS version values. |
| [2 - N+1]: => the max virtual voltage corner value corresponding to each fuse corner |
| for this speed bin, ordered from lowest voltage corner to highest |
| voltage corner. |
| No CPR target quotient scaling is applied on chips which have a speed bin + PVS version |
| pair that does not appear in one of the tuples in this property. If the property is |
| specified, then quotient scaling is enabled for the highest voltage corner. If this property is |
| not specified, then no quotient scaling can take place. |
| - qcom,cpr-corner-map: Array of elements of fuse corner value for each virtual corner. |
| The location or 1-based index of an element in the list corresponds to |
| the virtual corner value. For example, the first element in the list is the fuse corner |

| - qcom,cpr-corner-frequency-map: Array of tuples in which a tuple describes a corner to application processor frequency |
| mapping. |
| The 2 elements in one tuple are: |

| [3]: => fuse reading method, 0 for direct reading or 1 for SCM reading. |
| - qcom,cpr-voltage-ceiling-override: Array of (N+2)-tuples in which each tuple maps a CPU speed bin and PVS version |
| to the ceiling voltage to apply for each virtual voltage corner. The value N |
| corresponds to the number of virtual corners as specified by the number of elements |
| in the qcom,cpr-corner-map property. |
| The elements in one tuple are: |
| [0]: => the speed bin of the CPU. It may use the value 0xffffffff as a |
| wildcard to match any speed bin values. |
| [1]: => the PVS version of the CPU. It may use the value 0xffffffff as a |
| wildcard to match any PVS version values. |
| [2 - N+1]: => the ceiling voltage value in microvolts corresponding to each virtual |
| corner for this speed bin, ordered from lowest voltage corner to |
| highest voltage corner. |
| No ceiling override is applied on chips which have a speed bin + PVS version |
| pair that does not appear in one of the tuples in this property. If the property is |
| specified and the speed bin + PVS version matches, then the per-virtual-corner ceiling |
| voltages will be used in place of the per-fuse-corner ceiling voltages defined in the |
| qcom,cpr-voltage-ceiling property. If this property is not specified, then the |
| per-fuse-corner ceiling voltages will always be used. |
| - qcom,cpr-voltage-floor-override: Array of (N+2)-tuples in which each tuple maps a CPU speed bin and PVS version |
| to the floor voltage to apply for each virtual voltage corner. The value N |
| corresponds to the number of virtual corners as specified by the number of elements |
| in the qcom,cpr-corner-map property. |
| The elements in one tuple are: |
| [0]: => the speed bin of the CPU. It may use the value 0xffffffff as a |
| wildcard to match any speed bin values. |
| [1]: => the PVS version of the CPU. It may use the value 0xffffffff as a |
| wildcard to match any PVS version values. |
| [2 - N+1]: => the floor voltage value in microvolts corresponding to each virtual |
| corner for this speed bin, ordered from lowest voltage corner to |
| highest voltage corner. |
| No floor override is applied on chips which have a speed bin + PVS version |
| pair that does not appear in one of the tuples in this property. If the property is |
| specified and the speed bin + PVS version matches, then the per-virtual-corner floor |
| voltages will be used in place of the per-fuse-corner floor voltages defined in the |
| qcom,cpr-voltage-floor property. If this property is not specified, then the |
| per-fuse-corner floor voltages will always be used. |
| - qcom,cpr-floor-to-ceiling-max-range: Array of integer tuples of floor-to-ceiling max range values in microvolts |
| to be subtracted from the ceiling voltage values of each virtual corner. |
| Supported values are those greater than or equal 0, or (-1). The value 0 for a corner |
| implies that the floor value for that corner has to equal to its ceiling value. |
| The value (-1) for a corner implies that no modification to the default floor voltage |
| is required. The elements in a tuple are ordered from lowest voltage corner to highest |
| voltage corner. Each tuple must be of the length equal to the number of virtual corners |
| as specified by the number of elements in the qcom,cpr-corner-map property. If the |
| qcom,cpr-fuse-version-map property is specified, then |
| qcom,cpr-dynamic-floor-override-adjustment must contain the same number of |
| tuples as qcom,cpr-fuse-version-map. These tuples are then mapped one-to-one in the |
| order specified. E.g. if the second qcom,cpr-fuse-version-map tuple matches |
| for a given device, then voltage adjustments defined in the second |
| qcom,cpr-dynamic-floor-override-adjustment tuple will be applied. If the |
| qcom,cpr-fuse-version-map property is not specified, then |
| qcom,cpr-dynamic-floor-override-adjustment must contain a single tuple which |
| is then applied unconditionally. |
| - qcom,cpr-virtual-corner-init-voltage-adjustment: Array of integer tuples of voltage adjustments in microvolts to be |
| added to the initial voltage values of each virtual corner. The elements |
| in a tuple are ordered from lowest voltage corner to highest voltage corner. |
| Each tuple must be of the length equal to the number of virtual corners as |
| specified by the number of elements in the qcom,cpr-corner-map property. If the |
| qcom,cpr-fuse-version-map property is specified, then |
| qcom,cpr-virtual-corner-init-voltage-adjustment must contain the same number of |
| tuples as qcom,cpr-fuse-version-map. These tuples are then mapped one-to-one in the |
| order specified. E.g. if the second qcom,cpr-fuse-version-map tuple matches |
| for a given device, then voltage adjustments defined in the second |
| qcom,cpr-virtual-corner-init-voltage-adjustment tuple will be applied. If the |
| qcom,cpr-fuse-version-map property is not specified, then |
| qcom,cpr-virtual-corner-init-voltage-adjustment must contain a single tuple which |

| Each tuple must be of the length equal to the number of virtual corners as |
| specified by the number of elements in the qcom,cpr-corner-map property. |
| If the qcom,cpr-fuse-version-map property is specified, then |
| qcom,cpr-virtual-corner-quotient-adjustment must contain the same number of tuples as |
| qcom,cpr-fuse-version-map. These tuples are then mapped one-to-one in the |
| order specified. E.g. if the second qcom,cpr-fuse-version-map tuple matches |
| for a given device, then quotient adjustments defined in the second |
| qcom,cpr-virtual-corner-quotient-adjustment tuple will be applied. If the |
| qcom,cpr-fuse-version-map property is not specified, then |
| qcom,cpr-virtual-corner-quotient-adjustment must contain a single tuple which is then |
| applied unconditionally. |
| - qcom,cpr-cpus: Array of CPU phandles which correspond to the cores that this cpr-regulator |
| device must monitor when adjusting the voltage and/or target quotient based |
| upon the number of online cores or make sure that one of them must be online |
| when performing de-aging measurements. This property must be specified in order to |
| utilize the qcom,cpr-online-cpu-virtual-corner-init-voltage-adjustment or |
| qcom,cpr-online-cpu-virtual-corner-quotient-adjustment or qcom,cpr-aging-sensor-id properties. |
| - qcom,cpr-online-cpu-virtual-corner-init-voltage-adjustment: Array of tuples where each tuple specifies |
| the voltage adjustment for each corner. These adjustments apply to the |
| initial voltage of each corner. The size of each tuple must be equal |
| to qcom,cpr-fuse-corners if consumers request fuse corners or the length of |
| qcom,cpr-corner-map if consumers request virtual corners. In each tuple, the |
| value corresponds to the voltage adjustment when running at that corner at |
| init, from lowest to highest. The tuples must be organized into 1 group if |
| qcom,cpr-fuse-version-map is not specified or the same number of groups as |
| the number of tuples in qcom,cpr-fuse-version-map. The i-th group of tuples |
| corresponds to the voltage adjustments for i-th fuse version map tuple. In |
| each group, there are 1 plus length of qcom,cpr-cpus tuples, each tuple |
| corresponds to the number of cores online, from 0 to the number of elements |
| in qcom,cpr-cpus. |
| - qcom,cpr-online-cpu-init-voltage-as-ceiling: Boolean which indicates that the ceiling voltage used for a |
| given virtual corner may be reduced to the per number of cores online, |
| per-virtual corner ceiling voltage value. This property takes precedence |
| over qcom,cpr-scaled-init-voltage-as-ceiling if both are specified. |
| - qcom,cpr-online-cpu-virtual-corner-quotient-adjustment: Array of tuples where each tuple specifies |
| the quotient adjustment for each corner. These adjustments will be applied |
| to each corner at run time. The size of each tuple must be equal to |
| qcom,cpr-fuse-corners if consumers request fuse corners or the length of |
| qcom,cpr-corner-map if consumers request virtual corners. In each tuple, |
| the value corresponds to the quotient adjustment when running at that corner, |
| from lowest to highest. The tuples must be organized into 1 group if |
| qcom,cpr-fuse-version-map is not specified or the same number of groups |
| as the number of tuples in qcom,cpr-fuse-version-map. The i-th group of |
| tuples corresponds to the quotient adjustments for i-th fuse version map |
| tuple. In each group, there are 1 plus length of qcom,cpr-cpus tuples, |
| each tuple corresponds to the number of cores online, from 0 to the |
| number of elements in qcom,cpr-cpus. |
| - qcom,cpr-init-voltage-as-ceiling: Boolean which indicates that the ceiling voltage used for a given virtual |
| corner may be reduced to the per-fuse-corner initial voltage fuse value. |
| - qcom,cpr-scaled-init-voltage-as-ceiling: Boolean which indicates that the ceiling voltage used for a given |
| virtual corner may be reduced to the interpolated, per-virtual-corner initial |
| voltage value. Note that if both qcom,cpr-init-voltage-as-ceiling and |
| qcom,cpr-scaled-init-voltage-as-ceiling are specified, then |
| qcom,cpr-scaled-init-voltage-as-ceiling will take precedence since the interpolated |
| voltages are necessarily less than or equal to the fused initial voltage values. |
| - qcom,cpr-voltage-scaling-factor-max: Array of values which define the maximum allowed scaling factor to apply |
| when calculating per-corner initial voltage values for each fuse corner. The |
| array must be of length equal to the value of the qcom,cpr-fuse-corners property. |
| Each element in the array maps to the fuse corners in increasing order. |
| The elements have units of uV/MHz. Each element corresponds to 'max_factor' in |
| the following equation: |
| init_voltage_min(f) = fuse_init_voltage(f) - (fuse_f_max - f) * max_factor |
| If this property is not specified, then the initial voltage for each virtual |
| corner will be set to the initial voltage of the associated fuse corner. |
| - qcom,cpr-quot-adjust-scaling-factor-max: Array of values which define the maximum allowed scaling factor to |
| apply when calculating per-virtual-corner target quotients for each fuse |
| corner. Two data formats are allowed for this property. The primary one |
| requires that the array be of length equal to the value of the |
| qcom,cpr-fuse-corners property. When using this format, each element in the |
| array maps to the fuse corners in increasing order. The second depreciated |
| format allows for only a single element to be specified which defines the |
| maximum scaling factor for the highest fuse corner. In this case, a value of |
| 0 is assumed for the lower fuse corners. The elements of this property have |
| units of QUOT/GHz. Each element corresponds to 'max_factor' in the following |
| equation: |
| quot_min(f) = fuse_quot(f) - (fuse_f_max - f) * max_factor / 1000 |
| where f and fuse_f_max have units of MHz. |
| This property is required if qcom,cpr-speed-bin-max-corners is present. |
| - qcom,cpr-fuse-init-voltage: Array of quadruples in which each quadruple specifies a fuse location to |
| read in order to get an initial voltage for a fuse corner. The fuse values |
| are encoded as voltage steps higher or lower than the voltages defined in |
| qcom,cpr-voltage-ceiling. Each step corresponds to the voltage defined by |
| the qcom,cpr-init-voltage-step property. |
| The 4 elements in one quadruple are: |
| [0]: => the fuse row number of the bits |
| [1]: => LSB bit position of the bits |
| [2]: => number of the bits |
| [3]: => fuse reading method, 0 for direct reading or 1 for SCM reading |
| The quadruples are ordered from the lowest voltage fuse corner to the |
| highest voltage fuse corner. |
| A given cpr-regulator device must have either qcom,cpr-fuse-init-voltage |
| specified or qcom,pvs-voltage-table (and its associated properties). |
| - qcom,cpr-fuse-redun-init-voltage: Array of quadruples in which each quadruple specifies a fuse location |
| to read in order to get the redundant initial voltage for a fuse corner. |
| This property is the same as qcom,cpr-fuse-init-voltage except that it is |
| only utilized if a chip is configured to use the redundant set of fuse |
| values. This property is required if qcom,cpr-fuse-redun-sel and |
| qcom,cpr-fuse-init-voltage are specified. |
| - qcom,cpr-init-voltage-ref: Array of reference voltages in microvolts used when decoding the initial |
| voltage fuse values. The elements in the array are ordered from lowest |
| voltage corner to highest voltage corner. This property must be of length |
| defined by qcom,cpr-fuse-corners. |
| This property is required if qcom,cpr-fuse-init-voltage is present. |
| - qcom,cpr-init-voltage-step: The voltage step size in microvolts of the CPR initial voltage fuses described by the |
| qcom,cpr-fuse-init-voltage property. |

| - mem-acc-supply: Regulator to vote for the memory accelerator configuration. |
| Not Present: memory accelerator configuration not supported. |
| - qcom,mem-acc-corner-map: Array of integer which defines the mapping from mem-acc corner value for each |
| virtual corner. Each element is a mem-acc state for the corresponding virtual corner. |
| The elements in the array are ordered from lowest voltage corner to highest voltage corner. |
| - qcom,fuse-remap-source: Array of quadruples in which each quadruple specifies a fuse location to |
| remap. The 4 elements in one quadruple are: |
| [0]: => the fuse row number of the bits |
| [1]: => LSB bit position of the bits |
| [2]: => the number of bits |
| [3]: => fuse reading method, 0 for direct reading or 1 for SCM reading |
| The fuse bits for all quadruples are packed together in the order specified |
| into 64-bit virtual fuse rows beginning at the row number defined in the |
| qcom,fuse-remap-base-row property. The remapped rows may be used by any |
| other properties. |
| Example: |
| qcom,fuse-remap-base-row = <1000>; |
| qcom,fuse-remap-source = |
| <13 57 2 0>, |
| <14 30 3 0>, |
| <20 1 7 0>, |
| <40 47 120 0>; |
| |
| This results in the following bit remapping: |
| |
| Row Bits Remap Row Remap Bits |
| 13 57..58 --> 1000 0..1 |
| 14 30..32 --> 1000 2..4 |
| 20 1..7 --> 1000 5..11 |

| 41 0..34 --> 1000 29..63 |
| 41 35..63 --> 1001 0..28 |
| 42 0..34 --> 1001 29..63 |
| 42 35..38 --> 1002 0..3 |
| |
| A tuple like this could then be used to reference some of the |
| concatenated bits from rows 13, 14, and 20: |
| |
| qcom,cpr-fuse-init-voltage = <1000 0 6 0>; |
| - qcom,fuse-remap-base-row: Integer which defines the virtual row number to use as a base when remapping |
| fuse bits. The remap base row number can be any value as long as it is |
| greater than all of the real row numbers addressed in other properties of |
| the cpr-regulator device node. This property is required if |
| qcom,fuse-remap-source is specified. |
| - qcom,cpr-quot-min-diff: Integer which defines the minimum target-quotient difference between |
| the highest and (highest - 1) fuse corner to keep CPR enabled. If this |
| property is not specified a default value of 50 is used. |
| - qcom,cpr-fuse-quot-offset: Array of quadruples in which each quadruple specifies a fuse location to |
| read in order to get the quotient offset for a fuse corner. The fuse values |
| are encoded as the difference between quotients of that fuse corner and its |
| adjacent lower fuse corner divided by an unpacking multiplier value defined |
| under qcom,cpr-fuse-quot-offset-scale property. |
| The 4 elements in one quadruple are: |
| [0]: => the fuse row number of the bits |
| [1]: => LSB bit position of the bits |
| [2]: => number of the bits |
| [3]: => fuse reading method, 0 for direct reading or 1 for SCM reading |
| The quadruples are ordered from the lowest fuse corner to the highest |
| fuse corner. |
| Quotient offset read from the fuse locations above can be overridden with |
| the property qcom,cpr-quot-adjust-scaling-factor-max. |
| - qcom,cpr-fuse-quot-offset-scale: Array of integer values which defines the multipliers to decode the quotient offsets |
| of each fuse corner. The elements in the array are ordered from the lowest voltage fuse corner |
| to the highest voltage fuse corner. If this property is not present, then all target quotient |
| parameters are assumed to have a multiplier of 1 (i.e. no decoding needed). |
| - qcom,cpr-redun-fuse-quot-offset: Array of quadruples in which each quadruple specifies a fuse location to |
| read in order to get the redundant quotient offset for a fuse corner. This |
| property is the same as qcom,cpr-fuse-quot-offset except that it is only |
| utilized if a chip is configured to use the redundant set of fuse values. |
| - qcom,cpr-fuse-min-quot-diff: Array of values which define the minimum difference allowed between the adjusted |
| quotients of the fuse corners. The length of the array should be equal to the value |
| of the qcom,cpr-fuse-corners property. Where each element in the array maps to the |
| fuse corners in increasing order. |
| - qcom,cpr-min-quot-diff-adjustment: Array of integer tuples of target quotient offsets to be added to |
| the adjusted target quotients of each fuse corner. When the quotient difference |
| between two adjacent fuse corners is insufficient, the quotient for the higher fuse corner is |
| replaced with that of the lower fuse corner plus the adjustment value. |
| The elements in a tuple are ordered from lowest voltage corner to highest voltage corner. |
| Each tuple must be of the length defined by qcom,cpr-fuse-corners. |
| If the qcom,cpr-fuse-version-map property is specified, then qcom,cpr-min-quot-diff-adjustment |
| must contain the same number of tuples as qcom,cpr-fuse-version-map. These tuples are then mapped |
| one-to-one in the order specified. E.g. if the second qcom,cpr-fuse-version-map tuple matches |
| for a given device, then the quotient adjustments defined in the |
| second qcom,cpr-min-quot-diff-adjustment tuple will be applied. If the |
| qcom,cpr-fuse-version-map property is not specified, then |
| qcom,cpr-min-quot-diff-adjustment must contain a single tuple which is then |
| applied unconditionally. The qcom,cpr-min-quot-diff-adjustment property must be specified |
| if the qcom,cpr-fuse-min-quot-diff property is specified. |
| - qcom,cpr-skip-voltage-change-during-suspend: Boolean property which indicates that the CPR voltage |
| should not be adjusted based upon the number of online cores while |
| entering or exiting system suspend. |
| - rpm-apc-supply: Regulator to notify RPM of the APC operating |
| corner |

| cpr-regulator device or neither must be specified. |
| - vdd-vsens-corner-supply: Regulator to specify the current operating fuse corner to the Voltage Sensor. |
| - vdd-vsens-voltage-supply: Regulator to specify the corner floor/ceiling voltages to the Voltage Sensor. |
| - qcom,cpr-aging-sensor-id: Array of CPR sensor IDs to be used in the CPR de-aging algorithm. The number |
| of values should be equal to number of sensors selected for age calibration. |
| If this property is not specified, then the de-aging procedure is not enabled. |
| - qcom,cpr-de-aging-allowed: Integer values that specify whether the CPR de-aging procedure is allowed or |
| not for a particular fuse revision. If the qcom,cpr-fuse-version-map |
| property is specified, then qcom,cpr-de-aging-allowed must contain the same number |
| of elements as there are tuples in qcom,cpr-fuse-version-map. If qcom,cpr-fuse-version-map |
| is not specified, then qcom,cpr-de-aging-allowed must contain a single value that |
| is used unconditionally. An element value of 1 means that the CPR de-aging procedure |
| can be performed for parts with the corresponding fuse revision. An element value of 0 |
| means that CPR de-aging cannot be performed. |
| This property is required if the qcom,cpr-aging-sensor-id property has been specified. |
| - qcom,cpr-aging-ref-corner: The vdd-apc-supply reference virtual voltage corner to be set during the CPR de-aging |
| measurements. This corner value is needed to set appropriate voltage on |
| the dependent voltage rails such as vdd-mx and mem-acc. |

| - qcom,cpr-aging-ref-voltage: The vdd-apc-supply reference voltage in microvolts to be set during the |
| CPR de-aging measurements. |
| This property is required if the qcom,cpr-aging-sensor-id property has been specified. |
| - qcom,cpr-max-aging-margin: The maximum allowed aging voltage margin in microvolts. This is used to limit |
| the calculated aging voltage margin. |
| This property is required if the qcom,cpr-aging-sensor-id property has been specified. |
| - qcom,cpr-non-collapsible-sensors: Array of CPR sensor IDs which are in non-collapsible domain. The sensor IDs not |
| specified in the array should be bypassed for the de-aging procedure. The number of |
| elements should be less than or equal to 32. The values of the array elements should |
| be greater than or equal to 0 and less than or equal to 31. |

| This property can be required if the qcom,cpr-aging-sensor-id property has been specified. |
| - qcom,cpr-aging-ro-scaling-factor: The aging ring oscillator (RO) scaling factor with units of QUOT/V. |
| This value is used for calculating a voltage margin from RO measurements. |

| from the lowest to the highest RO. These values are used to calculate |
| the aging voltage margin adjustment for all of the ROs. Since CPR2 supports |
| exactly 8 ROs, the array must contain 8 elements corresponding to RO0 through RO7 in order. |
| If a given RO is unused for a fuse corner, then its scaling factor may be specified as 0. |
| This property is required if the qcom,cpr-aging-sensor-id property has been specified. |
| - qcom,cpr-aging-derate: Array of scaling factors which define the amount of derating to apply to the reference |

| order to get an initial quotient difference. The difference between quot min and quot max |
| is fused as the initial quotient difference. |
| The 4 elements in one quadruple are: |
| [0]: => the fuse row number of the bits |
| [1]: => LSB bit position of the bits |
| [2]: => number of the bits |
| [3]: => fuse reading method, 0 for direct reading or 1 for SCM reading |
| The number of quadruples should be equal to the number of values specified in |
| the qcom,cpr-aging-sensor-id property. This property is required if |
| the qcom,cpr-aging-sensor-id property has been specified. |
