[PATCH v4 2/2] dt-bindings: clk: intel: Add bindings document & header file for CGU
From: Rahul Tanwar
Date: Thu Jan 30 2020 - 04:06:24 EST
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.
