Add the policy for regulator DT such that if device have multiple regulator and its binding contains a child node that describes each regulator then each regulator child node must have the property "regulator-compatible" which matches with regulator name of their hardware counterparts. Modify the DT documentation of regulator devices to reflect this policy.

TPS6586x family of regulators
|
|
|
|
Required properties:
|
|
- compatible: "ti,tps6586x"
|
|
- reg: I2C slave address
|
|
- interrupts: the interrupt outputs of the controller
|
|
- #gpio-cells: number of cells to describe a GPIO
|
|
- gpio-controller: mark the device as a GPIO controller
|
|
- regulators: list of regulators provided by this controller, must have
|
|
property "regulator-compatible" to match their hardware counterparts:
|
|
sm[0-2], ldo[0-9] and ldo_rtc
|
|
|
|
Each regulator is defined using the standard binding for regulators.
|
|
|
|
Example:
|
|
|
|
pmu: tps6586x@34 {
|
|
compatible = "ti,tps6586x";
|
|
reg = <0x34>;
|
|
interrupts = <0 88 0x4>;
|
|
|
|
#gpio-cells = <2>;
|
|
gpio-controller;
|
|
|
|
regulators {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
