-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>;

The definition of "xxx-in-supply" was generic, thus define in detail the possible cases for each chip variant. Also document that the only possible I2C slave address is 0x60 as per the datasheet and fix the second example accordingly.
