Hi,
Convert Maxim MAX77686 bindings to dtschema. The MFD patch (2/2)
depends on regulator, so this should go via one tree.
Changes since v2:
1. Rebased.
Best regards,
Krzysztof

-Binding for Maxim MAX77686 regulators
-
-This is a part of the device tree bindings of MAX77686 multi-function device.
-More information can be found in ../mfd/max77686.txt file.
-
-The MAX77686 PMIC has 9 high-efficiency Buck and 26 Low-DropOut (LDO)
-regulators that can be controlled over I2C.
-
-Following properties should be present in main device node of the MFD chip.
-
-Optional node:
-- voltage-regulators : The regulators of max77686 have to be instantiated
- under subnode named "voltage-regulators" using the following format.
-
- regulator_name {
- regulator-compatible = LDOn/BUCKn
- standard regulator constraints....
- };
- refer Documentation/devicetree/bindings/regulator/regulator.txt
-
- The regulator node's name should be initialized with a string
-to get matched with their hardware counterparts as follow:
-
- -LDOn : for LDOs, where n can lie in range 1 to 26.
- example: LDO1, LDO2, LDO26.
- -BUCKn : for BUCKs, where n can lie in range 1 to 9.
- example: BUCK1, BUCK5, BUCK9.
-
- Regulators which can be turned off during system suspend:
- -LDOn : 2, 6-8, 10-12, 14-16,
- -BUCKn : 1-4.
- Use standard regulator bindings for it ('regulator-off-in-suspend').
-
- LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
- control. To turn this feature on this property must be added to the regulator
- sub-node:
- - maxim,ena-gpios : one GPIO specifier enable control (the gpio
- flags are actually ignored and always
- ACTIVE_HIGH is used)
-
-Example:
-
- max77686: pmic@9 {
- compatible = "maxim,max77686";
- interrupt-parent = <&wakeup_eint>;
- interrupts = <26 IRQ_TYPE_LEVEL_LOW>;
- reg = <0x09>;
-
- voltage-regulators {
- ldo11_reg: LDO11 {
- regulator-name = "vdd_ldo11";
- regulator-min-microvolt = <1900000>;
- regulator-max-microvolt = <1900000>;
- regulator-always-on;
- };
-
- buck1_reg: BUCK1 {
- regulator-name = "vdd_mif";
- regulator-min-microvolt = <950000>;
- regulator-max-microvolt = <1300000>;
- regulator-always-on;
- regulator-boot-on;
- };
-
- buck9_reg: BUCK9 {
- regulator-name = "CAM_ISP_CORE_1.2V";
- regulator-min-microvolt = <1000000>;
- regulator-max-microvolt = <1200000>;
- maxim,ena-gpios = <&gpm0 3 GPIO_ACTIVE_HIGH>;

-Maxim MAX77686 multi-function device
-
-MAX77686 is a Multifunction device with PMIC, RTC and Charger on chip. It is
-interfaced to host controller using i2c interface. PMIC and Charger submodules
-are addressed using same i2c slave address whereas RTC submodule uses
-different i2c slave address,presently for which we are statically creating i2c
-client while probing.This document describes the binding for mfd device and
-PMIC submodule.
-
-Bindings for the built-in 32k clock generator block and
-regulators are defined in ../clk/maxim,max77686.txt and
-../regulator/max77686.txt respectively.
-
-Required properties:
-- compatible : Must be "maxim,max77686";
-- reg : Specifies the i2c slave address of PMIC block.
-- interrupts : This i2c device has an IRQ line connected to the main SoC.
-
-Example:
-
- max77686: pmic@9 {
- compatible = "maxim,max77686";
- interrupt-parent = <&wakeup_eint>;
- interrupts = <26 IRQ_TYPE_LEVEL_LOW>;
- reg = <0x09>;
