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