Qualcomm Technologies, Inc. SPMI PMIC clock divider (clkdiv)

clkdiv configures the clock frequency of a set of outputs on the PMIC.
These clocks are typically wired through alternate functions on
gpio pins.

=======================
Properties
=======================

- compatible
	Usage:      required
	Value type: <string>
	Definition: must be "qcom,spmi-clkdiv".

- reg
	Usage:      required
	Value type: <prop-encoded-array>
	Definition: base address of CLKDIV peripherals.

- qcom,num-clkdivs
	Usage:      required
	Value type: <u32>
	Definition: number of CLKDIV peripherals.

- clocks:
	Usage: required
	Value type: <prop-encoded-array>
	Definition: reference to the xo clock.

- clock-names:
	Usage: required
	Value type: <stringlist>
	Definition: must be "xo".

- #clock-cells:
	Usage: required
	Value type: <u32>
	Definition: shall contain 1.
