| 2 | |
| 3 | Required properties: |
| 4 | - compatible: "ti,tps65910" or "ti,tps65911" |
| 5 | - reg: I2C slave address |
| 6 | - interrupts: the interrupt outputs of the controller |
| 7 | - #gpio-cells: number of cells to describe a GPIO, this should be 2. |
| 8 | The first cell is the GPIO number. |
| 9 | The second cell is used to specify additional options <unused>. |
| 10 | - gpio-controller: mark the device as a GPIO controller |
| 11 | - #interrupt-cells: the number of cells to describe an IRQ, this should be 2. |
| 12 | The first cell is the IRQ number. |
| 13 | The second cell is the flags, encoded as the trigger masks from |
| 14 | Documentation/devicetree/bindings/interrupts.txt |
| 15 | - regulators: This is the list of child nodes that specify the regulator |
| 16 | initialization data for defined regulators. Not all regulators for the given |
| 17 | device need to be present. The definition for each of these nodes is defined |
| 18 | using the standard binding for regulators found at |
| 19 | Documentation/devicetree/bindings/regulator/regulator.txt. |
| 20 | |
| 21 | The valid names for regulators are: |
| 22 | tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1, |
| 23 | vaux2, vaux33, vmmc |
| 24 | tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5, |
| 25 | ldo6, ldo7, ldo8 |
| 26 | |
| 27 | Optional properties: |
| 28 | - ti,vmbch-threshold: (tps65911) main battery charged threshold |
| 29 | comparator. (see VMBCH_VSEL in TPS65910 datasheet) |
| 30 | - ti,vmbch2-threshold: (tps65911) main battery discharged threshold |
| 31 | comparator. (see VMBCH_VSEL in TPS65910 datasheet) |
| 32 | - ti,en-gpio-sleep: enable sleep control for gpios |
| 33 | There should be 9 entries here, one for each gpio. |
| 34 | |
| 35 | Regulator Optional properties: |
| 36 | - ti,regulator-ext-sleep-control: enable external sleep |
| 37 | control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)] |
| 38 | If this property is not defined, it defaults to 0 (not enabled). |
| 39 | |

| 54 | ti,vmbch-threshold = 0; |
| 55 | ti,vmbch2-threshold = 0; |
