1Maxim MAX77686 multi-function device
2
3MAX77686 is a Mulitifunction device with PMIC, RTC and Charger on chip. It is
4interfaced to host controller using i2c interface. PMIC and Charger submodules
5are addressed using same i2c slave address whereas RTC submodule uses
6different i2c slave address,presently for which we are statically creating i2c
7client while probing.This document describes the binding for mfd device and
8PMIC submodule.
9
10Required properties:
11- compatible : Must be "maxim,max77686";
12- reg : Specifies the i2c slave address of PMIC block.
13- interrupts : This i2c device has an IRQ line connected to the main SoC.
14- interrupt-parent : The parent interrupt controller.
15
16Optional node:
17- voltage-regulators : The regulators of max77686 have to be instantiated
18 under subnode named "voltage-regulators" using the following format.
19
20 regulator_name {
21 regulator-compatible = LDOn/BUCKn
22 standard regulator constraints....
23 };
24 refer Documentation/devicetree/bindings/regulator/regulator.txt
25
26 The regulator-compatible property of regulator should initialized with string
27to get matched with their hardware counterparts as follow:
28
29 -LDOn : for LDOs, where n can lie in range 1 to 26.
30 example: LDO1, LDO2, LDO26.
31 -BUCKn : for BUCKs, where n can lie in range 1 to 9.
32 example: BUCK1, BUCK5, BUCK9.
