Set tps65217 PMIC status to OFF if power enable toggle is supported. By setting this bit to 1 to enter PMIC to OFF state when PWR_EN pin is pulled low. Also adds a DT flag to specify that device pmic supports shutdown control or not.

TPS65217 family of regulators
|
|
|
|
Required properties:
|
|
- compatible: "ti,tps65217"
|
|
- reg: I2C slave address
|
|
- regulators: list of regulators provided by this controller, must be named
|
|
after their hardware counterparts: dcdc[1-3] and ldo[1-4]
|
|
- 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.
|
|
|
|
Optional properties:
|
|
- ti,pmic-shutdown-controller: Telling the PMIC to shutdown on PWR_EN toggle.
|
|
|
|
The valid names for regulators are:
|
|
tps65217: dcdc1, dcdc2, dcdc3, ldo1, ldo2, ldo3 and ldo4
|
|
|
|
Each regulator is defined using the standard binding for regulators.
|
|
|
|
Example:
|
|
|
|
tps: tps@24 {
|
|
compatible = "ti,tps65217";
|
|
ti,pmic-shutdown-controller;
