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.

+Maxim MAX77802 multi-function device
+
+The Maxim MAX77802 is a power management chip (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.
+
+Binding for the built-in 32k clock generator block is defined separately
+in the bindings/clk/maxim,max77802.txt file and binding for the regulators
+is defined in the bindings/regulator/max77802.txt file.
+
+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.
+- interrupt-parent : The parent interrupt controller.
+
+Example:
+
+ max77802@09 {

Sigh, I'm tired of saying this over and over again: please don't name the nodes with teh chip names. The ePAPR standard says: "The name of a node should be somewhat generic, reflecting the function of the device and not its 3 precise programming model."

WBR, Sergei
