Add DT property "ti,system-power-controller" telling whether or not this pmic is in charge of controlling the system power, so the power off routine can be hooked up to system call "pm_power_off".

TPS65910 Power Management Integrated Circuit
|
|
|
|
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 regulator is matched with the regulator-compatible.
|
|
|
|
The valid regulator-compatible values are:
|
|
tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1,
|
|
vaux2, vaux33, vmmc
|
|
tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5,
|
|
ldo6, ldo7, ldo8
|
|
|
|
- xxx-supply: Input voltage supply regulator.
|
|
These entries are require if regulators are enabled for a device. Missing of these
|
|
properties can cause the regulator registration fails.
|
|
If some of input supply is powered through battery or always-on supply then
|
|
also it is require to have these parameters with proper node handle of always
|
|
on power supply.
|
|
tps65910:
|
|
vcc1-supply: VDD1 input.
|
|
vcc2-supply: VDD2 input.
|
|
vcc3-supply: VAUX33 and VMMC input.
|
|
vcc4-supply: VAUX1 and VAUX2 input.
|
|
vcc5-supply: VPLL and VDAC input.
|
|
vcc6-supply: VDIG1 and VDIG2 input.
|
|
vcc7-supply: VRTC input.
|
|
vccio-supply: VIO input.
|
|
tps65911:
|
|
vcc1-supply: VDD1 input.
|
|
vcc2-supply: VDD2 input.
|
|
vcc3-supply: LDO6, LDO7 and LDO8 input.
|
|
vcc4-supply: LDO5 input.
|
|
vcc5-supply: LDO3 and LDO4 input.
|
|
vcc6-supply: LDO1 and LDO2 input.
|
|
vcc7-supply: VRTC input.
|
|
vccio-supply: VIO input.
|
|
|
|
Optional properties:
|
|
- ti,vmbch-threshold: (tps65911) main battery charged threshold
|
|
comparator. (see VMBCH_VSEL in TPS65910 datasheet)
|
|
- ti,vmbch2-threshold: (tps65911) main battery discharged threshold
|
|
comparator. (see VMBCH_VSEL in TPS65910 datasheet)
|
|
- ti,en-ck32k-xtal: enable external 32-kHz crystal oscillator (see CK32K_CTRL
|
|
in TPS6591X datasheet)
|
|
- ti,en-gpio-sleep: enable sleep control for gpios
|
|
There should be 9 entries here, one for each gpio.
|
|
- ti,system-power-controller: Telling whether or not this pmic is controlling
|
|
the system power.
|
|
|
|
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).
