mfd: Add LP87565 PMIC support
The LP87565 chip is a power management IC for Portable Navigation Systems and Tablet Computing devices. It contains the following components: - Configurable Bucks(Single and multi-phase). - Configurable General Purpose Output Signals (GPO). The LP87565-Q1 variant device uses two 2-phase outputs configuration, Buck0 is master for Buck0/1 output and Buck2 is master for Buck2/3 output.

+TI LP87565 PMIC MFD driver
+
+Required properties:
+ - compatible: "ti,lp87565", "ti,lp87565-q1"
+ - reg: I2C slave address.
+ - gpio-controller: Marks the device node as a GPIO Controller.
+ - #gpio-cells: Should be two. The first cell is the pin number and
+ the second cell is used to specify flags.
+ See ../gpio/gpio.txt for more information.
+ - xxx-in-supply: Phandle to parent supply node of each regulator
+ populated under regulators node. xxx should match
+ the supply_name populated in driver.
+Example:
+
+lp87565_pmic: pmic@60 {
+ compatible = "ti,lp87565-q1";
+ reg = <0x60>;
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ buck10-in-supply = <&vsys_3v3>;
+ buck23-in-supply = <&vsys_3v3>;
+
+ regulators: regulators {
+ buck10_reg: buck10 {
+ /* VDD_MPU */
+ regulator-name = "buck10";
+ regulator-min-microvolt = <850000>;
+ regulator-max-microvolt = <1250000>;
+ regulator-always-on;

+
+ buck23_reg: buck23 {

+ regulator-min-microvolt = <850000>;
