Jonghwa Lee 80b022e29b regulator: max77693: Add max77693 regualtor driver.
This patch adds new regulator driver to support max77693 chip's regulators.
max77693 has two linear voltage regulators and one current regulator which
can be controlled through I2C bus. This driver also supports device tree.

Maxim MAX77693 multi-function device
MAX77693 is a Multifunction device with the following submodules:
- PMIC,
- CHARGER,
- LED,
- MUIC,
- HAPTIC
It is interfaced to host controller using i2c.
This document describes the bindings for the mfd device.
Required properties:
- compatible : Must be "maxim,max77693".
- reg : Specifies the i2c slave address of PMIC block.
- interrupts : This i2c device has an IRQ line connected to the main SoC.
- interrupt-parent : The parent interrupt controller.
Optional properties:
- regulators : The regulators of max77693 have to be instantiated under subnod
named "regulators" using the following format.
regulators {
regualtor-compatible = ESAFEOUT1/ESAFEOUT2/CHARGER
standard regulator constratints[*].
};
[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
Example:
max77693@66 {
compatible = "maxim,max77693";
reg = <0x66>;
interrupt-parent = <&gpx1>;
interrupts = <5 2>;
regulators {
esafeout@1 {
regulator-compatible = "ESAFEOUT1";
regulator-name = "ESAFEOUT1";
regulator-boot-on;
};
esafeout@2 {
regulator-compatible = "ESAFEOUT2";
regulator-name = "ESAFEOUT2";
};
charger@0 {
regulator-compatible = "CHARGER";
regulator-name = "CHARGER";
regulator-min-microamp = <60000>;
regulator-max-microamp = <2580000>;
regulator-boot-on;
};
};
};
