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";
