Subject: [PATCH v4 3/4] mfd: Add DT binding for Maxim MAX77802 IC
The MAX77802 is a chip that contains regulators, 2 32kHz clocks,
a RTC and an I2C interface to program the individual components.
The are already DT bindings for the regulators and clocks and
these reference to a bindings/mfd/max77802.txt file, that didn't
exist, for the details about the PMIC.

Changes in v4:
- Reword section about max77802 clock and regulator DT binding docs.
Suggested by Lee Jones.
- Align max77802 mfd required properties. Suggested by Lee Jones.
Changes in v3:
- Add Krzysztof Kozlowski Reviewed-by tag to patch #3.
- Capitalise all acronyms. Suggested by Lee Jones.
- Use relative path to refer other bindings. Suggested by Lee Jones.
- Use IRQ_TYPE_NONE instead of 0 in example. Suggested by Lee Jones.
Changes in v2:
- Use the correct "maxim,max77802" compatible string.
Suggested by Krzysztof Kozlowski
- Use a pmic generic node name for the max77802 node example.
Suggested by Sergei Shtylyov.

+Maxim MAX77802 multi-function device
+
+The Maxim MAX77802 is a Power Management IC (PMIC) that contains 10 high
+efficiency Buck regulators, 32 Low-DropOut (LDO) regulators used to power
+up application processors and peripherals, a 2-channel 32kHz clock outputs,
+a Real-Time-Clock (RTC) and a I2C interface to program the individual
+regulators, clocks outputs and the RTC.
+
+Bindings for the built-in 32k clock generator block and
+regulators are defined in ../clk/maxim,max77802.txt and
+../regulator/max77802.txt respectively.
+
+Required properties:
+- compatible : Must be "maxim,max77802"
+- reg : Specifies the I2C slave address of PMIC block.
+- interrupts : I2C device IRQ line connected to the main SoC.
+- interrupt-parent : The parent interrupt controller.
+
+Example:
+
+ max77802: pmic@09 {
+ compatible = "maxim,max77802";
+ interrupt-parent = <&intc>;
+ interrupts = <26 IRQ_TYPE_NONE>;
+ reg = <0x09>;
+ };
