Add device tree based initialization support for tps65023 regulators. Therefore add macros for regulator definition setting of_match and regulators_node members. Add initialization of regulator_desc data using these macros. Remove old regulator_desc initialization. Add device tree binding document for tps65023 regulators.

TPS65023 family of regulators
|
|
|
|
Required properties:
|
|
- compatible: Must be one of the following.
|
|
"ti,tps65020",
|
|
"ti,tps65021",
|
|
"ti,tps65023",
|
|
- reg: I2C slave address
|
|
- regulators: list of regulators provided by this controller, must be named
|
|
after their hardware counterparts: VDCDC[1-3] and LDO[1-2]
|
|
- regulators: This is the list of child nodes that specify the regulator
|
|
initialization data for defined regulators. The definition for each of
|
|
these nodes is defined using the standard binding for regulators found at
|
|
Documentation/devicetree/bindings/regulator/regulator.txt.
|
|
|
|
Each regulator is defined using the standard binding for regulators.
|
|
|
|
Example:
|
|
|
|
tps65023@48 {
|
|
compatible = "ti,tps65023";
|
|
reg = <0x48>;
|
|
|
|
regulators {
|
|
VDCDC1 {
|
|
regulator-name = "vdd_mpu";

|
|
regulator-min-microvolt = <1200000>;
|
|
regulator-max-microvolt = <1200000>;
|
|
};
|
|
|
|
VDCDC2 {
|
|
regulator-name = "vdd_core";
|
|

|
