Loongson-2 SoC clock control module is an integrated clock controller, which
generates and supplies to all modules.

compatible:
enum:
- loongson,ls2k0300-clk
- loongson,ls2k0500-clk
- loongson,ls2k-clk # This is for Loongson-2K1000

description:
The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/loongson,ls2k-clk.h
for the full list of Loongson-2 SoC clock IDs.
