Subject[PATCH v1 2/2] dt-bindings: clk: intel: Add bindings document & header file for CGU
Date
Clock generation unit(CGU) is a clock controller IP of Intel's Lightning
Mountain(LGM) SoC. Add DT bindings include file and document for CGU clock
controller driver of LGM.

+description: |
+ Lightning Mountain(LGM) SoC's Clock Generation Unit(CGU) driver provides
+ all means to access the CGU hardware module in order to generate a series
+ of clocks for the whole system and individual peripherals.
+
+ This binding uses the common clock bindings
