Subject: [PATCH v8 02/13] mfd: max77802: Add DT binding documentation

Add Device Tree binding documentation for Maxim 77802 PMIC.

Signed-off-by: Javier Martinez Canillas <javier.martinez@...labora.co.uk>
---

Changes since v7:
 - Remove information about DVS since that will be added as a follow up.

Changes since v6: None

Changes since v5:
 - Use max77686,* properties instead of max77802,* since the support is
   now in the max77686 driver and that IP defined the properties first.
 - Fix issues in DT binding documentation. Suggested by Andreas Farber.

Changes since v4: None

Changes since v3: None

Changes since v2:
 - Explain better the Dynamic Voltage Scaling (DVS) support in some Buck
   regulators and the max77802,pmic-buck-{dvs,selb}-gpios properties.
   Suggested by Mark Brown.

+Maxim MAX77802 multi-function device
+
+MAX77802 is a Multifunction device with PMIC, RTC and Charger on chip. It is
+interfaced to host controller using i2c interface. PMIC, Charger and RTC
+submodules are addressed using same i2c slave address.
+
+This document describes the binding for mfd device and PMIC submodule.
+
+Binding for the built-in 32k clock generator block is defined separately
+in bindings/clk/maxim,max77802.txt file.
+
+Required properties:
+- compatible : Must be "maxim,max77802";
+- reg : Specifies the i2c slave address of PMIC block.
+- interrupts : This i2c device has an IRQ line connected to the main SoC.
+- interrupt-parent : The parent interrupt controller.
+
+Optional node:
+- regulators : The regulators of max77802 have to be instantiated
+  under subnode named "regulators" using the following format.
+
+	regulator-name {
+		standard regulator constraints....
+	};
+	refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+  The regulator node name should be initialized with a string
+to get matched with their hardware counterparts as follow. The valid names are:
+
+	-LDOn 	:	for LDOs, where n can lie in range 1 to 35.
+			example: LDO1, LDO2, LDO35.
+	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 10.
+			example: BUCK1, BUCK5, BUCK10.
+Example:
+
+	max77802@09 {
+		compatible = "maxim,max77802";
+		interrupt-parent = <&wakeup_eint>;
+		interrupts = <26 0>;
+		reg = <0x09>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		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;
+			};
+	};
