+
+Description:
+
+The VL53L0X is a new generation Time-of-Flight
+(ToF) laser-ranging module housed in the
+smallest package on the market today, providing
+accurate distance measurement whatever the
+target reflectances unlike conventional
+technologies. It can measure absolute distances
+up to 2m, setting a new benchmark in ranging
+performance levels, opening the door to various
+new applications.
+The VL53L0X integrates a leading-edge SPAD
+array (Single Photon Avalanche Diodes) and
+embeds ST’s second generation FlightSenseTM
+patented technology.
+The VL53L0X’s 940 nm VCSEL emitter (Vertical
+Cavity Surface-Emitting Laser), is totally invisible
+to the human eye, coupled with internal physical
+infrared filters, it enables longer ranging
+distances, higher immunity to ambient light, and
+better robustness to cover glass optical crosstalk.
+
+Required properties:
+
+ - compatible		: Should be "st,stmvl53l0".
+ - reg			: i2c slave address of the device.

-* MCD (MobiCore Driver)
-
-t-base is an operating system running in the secure world (TrustZone).
-The t-base implementation consists of several components in the
-secure world and the non-secure world (kernel and user space). The
-MobiCore driver communicates with the t-base operating system that
-exists in TrustZone.
-
-Required properties:
-  - compatible: Should be "qcom,mcd"
-  - qcom,ce-hw-instance: should contain crypto HW instance
-  - qcom,ce-device: Device number
-  - clocks: Array of <clock_controller_phandle clock_reference> listing
-            all the clocks that are accesed by this subsystem.
-  - qcom,ce-opp-freq: indicates the CE operating frequency in Hz, changes from target to target.
-
-Example:
-	mcd {
-		compatible = "qcom,mcd";
-		qcom,ce-hw-instance = <0>;
-		qcom,ce-device = <0>;
-		clocks = <&clock_gcc clk_crypto_clk_src>,
-			 <&clock_gcc clk_gcc_crypto_clk>,
-			 <&clock_gcc clk_gcc_crypto_ahb_clk>,
-			 <&clock_gcc clk_gcc_crypto_axi_clk>;
-		clock-names = "core_clk_src", "core_clk",
-				"iface_clk", "bus_clk";
-		qcom,ce-opp-freq = <100000000>;

+- ti,palmas-override-powerhold: This is applicable for PMICs for which
+	GPIO7 is configured in POWERHOLD mode which has higher priority
+	over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON

+// SHA256/512 for ARMv8.
+//
+// Performance in cycles per processed byte and improvement coefficient
+// over code generated with "default" compiler:
+//
+//		SHA256-hw	SHA256(*)	SHA512
+// Apple A7	1.97		10.5 (+33%)	6.73 (-1%(**))
+// Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))
+// Cortex-A57	2.31		11.6 (+86%)	7.51 (+260%(***))
+// Denver	2.01		10.5 (+26%)	6.70 (+8%)
+// X-Gene			20.0 (+100%)	12.8 (+300%(***))
+// Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+//
+// (*)	Software SHA256 results are of lesser relevance, presented
+//	mostly for informational purposes.
+// (**)	The result is a trade-off: it's possible to improve it by
+//	10% (or by 1 cycle per round), but at the cost of 20% loss
+//	on Cortex-A53 (or by 4 cycles per round).
+// (***)	Super-impressive coefficients over gcc-generated code are
+//	indication of some compiler "pathology", most notably code
+//	generated with -mgeneral-regs-only is significanty faster
+//	and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+//	on Cortex-A53 (or by 4 cycles per round).
+// (***)	Super-impressive coefficients over gcc-generated code are

+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+ * A permission is a token that permits a receiver to read and/or write an area
+ * of memory within a Vsoc region.
+ *
+ * An fd_scoped permission grants both read and write access, and can be
+ * attached to a file description (see open(2)).
+ * Ownership of the area can then be shared by passing a file descriptor
+ * among processes.
+ *
+ * begin_offset and end_offset define the area of memory that is controlled by
+ * the permission. owner_offset points to a word, also in shared memory, that
+ * controls ownership of the area.
+ *
+ * ownership of the region expires when the associated file description is
+ * released.
+ *
+ * At most one permission can be attached to each file description.
+ *
+ * This is useful when implementing HALs like gralloc that scope and pass
+ * ownership of shared resources via file descriptors.
+ *
+ * The caller is responsibe for doing any fencing.
+ *
+ * The calling process will normally identify a currently free area of
+ * memory. It will construct a proposed fd_scoped_permission_arg structure:
+ *
+ *   begin_offset and end_offset describe the area being claimed
+ *
+ *   owner_offset points to the location in shared memory that indicates the
+ *   owner of the area.
+ *
+ *   owned_value is the value that will be stored in owner_offset iff the
+ *   permission can be granted. It must be different than VSOC_REGION_FREE.
+ *
+ * Two fd_scoped_permission structures are compatible if they vary only by
+ * their owned_value fields.
+ *
+ * The driver ensures that, for any group of simultaneous callers proposing
+ * compatible fd_scoped_permissions, it will accept exactly one of the
+ * propopsals. The other callers will get a failure with errno of EAGAIN.
+ *
+ * A process receiving a file descriptor can identify the region being
+ * granted using the VSOC_GET_FD_SCOPED_PERMISSION ioctl.

+ * Describes a signal table in shared memory. Each non-zero entry in the
+ * table indicates that the receiver should signal the futex at the given
+ * offset. Offsets are relative to the region, not the shared memory window.
+ *
+ * interrupt_signalled_offset is used to reliably signal interrupts across the
+ * vmm boundary. There are two roles: transmitter and receiver. For example,
+ * in the host_to_guest_signal_table the host is the transmitter and the
+ * guest is the receiver. The protocol is as follows:
+ *
+ * 1. The transmitter should convert the offset of the futex to an offset
+ *    in the signal table [0, (1 << num_nodes_lg2))
+ *    The transmitter can choose any appropriate hashing algorithm, including
+ *    hash = futex_offset & ((1 << num_nodes_lg2) - 1)
+ *
+ * 3. The transmitter should atomically compare and swap futex_offset with 0
+ *    at hash. There are 3 possible outcomes
+ *      a. The swap fails because the futex_offset is already in the table.
+ *         The transmitter should stop.
+ *      b. Some other offset is in the table. This is a hash collision. The
+ *         transmitter should move to another table slot and try again. One
+ *         possible algorithm:
+ *         hash = (hash + 1) & ((1 << num_nodes_lg2) - 1)
+ *      c. The swap worked. Continue below.
+ *
+ * 3. The transmitter atomically swaps 1 with the value at the
+ *    interrupt_signalled_offset. There are two outcomes:
+ *      a. The prior value was 1. In this case an interrupt has already been
+ *         posted. The transmitter is done.
+ *      b. The prior value was 0, indicating that the receiver may be sleeping.
+ *         The transmitter will issue an interrupt.
+ *
+ * 4. On waking the receiver immediately exchanges a 0 with the
+ *    interrupt_signalled_offset. If it receives a 0 then this a spurious
+ *    interrupt. That may occasionally happen in the current protocol, but
+ *    should be rare.
+ *
+ * 5. The receiver scans the signal table by atomicaly exchanging 0 at each
+ *    location. If a non-zero offset is returned from the exchange the
+ *    receiver wakes all sleepers at the given offset:
+ *      futex((int*)(region_base + old_value), FUTEX_WAKE, MAX_INT);
+ *
+ * 6. The receiver thread then does a conditional wait, waking immediately
+ *    if the value at interrupt_signalled_offset is non-zero. This catches cases
+ *    here additional  signals were posted while the table was being scanned.
+ *    On the guest the wait is handled via the VSOC_WAIT_FOR_INCOMING_INTERRUPT

- * When a -deadline entity is queued back on the runqueue, its runtime and

  *
- * The policy here is that we update the deadline of the entity only if:

- *    the entity exceed its bandwidth.
+ * Reasoning: a task may overrun the density if:

+ *
+ * Therefore, runtime can be adjusted to:
+ *     runtime = (dl_runtime / dl_deadline) * (deadline - t)
+ *
+ * In such way that runtime will be equal to the maximum density

+ * When a task is queued before the begin of the next period, using the
