+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:
+

+ #gpio-cells = <2>;
