Convert the MFD part of Maxim MAX77802 PMIC to DT schema format. The
example DTS was copied from existing DTS (exynos5800-peach-pi.dts), so
keep the license as GPL-2.0-only.

-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.
-
-Example:
-
- max77802: pmic@9 {
- compatible = "maxim,max77802";
- interrupt-parent = <&intc>;
- interrupts = <26 IRQ_TYPE_NONE>;
- reg = <0x09>;
- };

+description: |
+ This is a part of device tree bindings for Maxim MAX77802 Power Management
+ Integrated Circuit (PMIC).
+
+ The Maxim MAX77802 is a Power Management IC which includes voltage and
+ current regulators (10 high efficiency Buck regulators and 32 Low-DropOut
+ (LDO)), RTC and clock outputs.
+
+ The MAX77802 provides two 32.768khz clock outputs that can be controlled
+ (gated/ungated) over I2C. The clock IDs are defined as preprocessor macros
+ in dt-bindings/clock/maxim,max77802.h.
