|
|
||
| Required properties: | ||
| - compatible: "ti,tps65910" or "ti,tps65911" | ||
| - reg: I2C slave address | ||
| - interrupts: the interrupt outputs of the controller | ||
| - #gpio-cells: number of cells to describe a GPIO, this should be 2. | ||
| The first cell is the GPIO number. | ||
| The second cell is used to specify additional options <unused>. | ||
| - gpio-controller: mark the device as a GPIO controller | ||
| - #interrupt-cells: the number of cells to describe an IRQ, this should be 2. | ||
| The first cell is the IRQ number. | ||
| The second cell is the flags, encoded as the trigger masks from | ||
| Documentation/devicetree/bindings/interrupts.txt | ||
| - regulators: This is the list of child nodes that specify the regulator | ||
| initialization data for defined regulators. Not all regulators for the given | ||
| device need to be present. The definition for each of these nodes is defined | ||
| using the standard binding for regulators found at | ||
| Documentation/devicetree/bindings/regulator/regulator.txt. | ||
|
|
||
| The valid names for regulators are: | ||
| tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1, | ||

| comparator. (see VMBCH_VSEL in TPS65910 datasheet) | ||
| - ti,vmbch2-threshold: (tps65911) main battery discharged threshold | ||
| comparator. (see VMBCH_VSEL in TPS65910 datasheet) | ||
| - ti,en-gpio-sleep: enable sleep control for gpios | ||
| There should be 9 entries here, one for each gpio. | ||
|
|
||
| Regulator Optional properties: | ||
| - ti,regulator-ext-sleep-control: enable external sleep | ||
| control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)] | ||
| If this property is not defined, it defaults to 0 (not enabled). | ||

| Texas Instruments TWL6040 family | ||
|
|
||
| The TWL6040s are 8-channel high quality low-power audio codecs providing audio | ||
| and vibra functionality on OMAP4+ platforms. | ||

| data and commands. | ||
|
|
||
| Required properties: | ||
| - compatible : Must be "ti,twl6040"; | ||
| - reg: must be 0x4b for i2c address | ||
| - interrupts: twl6040 has one interrupt line connecteded to the main SoC | ||
