regulator: tps65023: add device tree support 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. Signed-off-by: Thomas Elste <thomas.elste@imms.de> Signed-off-by: Mark Brown <broonie@kernel.org>

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-always-on;
regulator-min-microvolt = <1200000>;
regulator-max-microvolt = <1200000>;
};
VDCDC2 {
regulator-name = "vdd_core";
regulator-always-on;
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
};
VDCDC3 {
regulator-name = "vdd_io";
regulator-always-on;
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
};
LDO1 {
regulator-name = "vdd_usb18";
regulator-always-on;
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
};
LDO2 {
regulator-name = "vdd_usb33";
regulator-always-on;
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
};
};
};
