-Qualcomm Technologies, Inc. Display Clock Controller Binding
-------------------------------------------------------------
-
-Required properties :
-
-- compatible : shall contain "qcom,sdm845-dispcc"
-- reg : shall contain base register location and length.
-- #clock-cells : from common clock binding, shall contain 1.
-- #reset-cells : from common reset binding, shall contain 1.
-- #power-domain-cells : from generic power domain binding, shall contain 1.

-Example:
- dispcc: clock-controller@af00000 {
- compatible = "qcom,sdm845-dispcc";
- reg = <0xaf00000 0x100000>;
- #clock-cells = <1>;
