[PATCH v3 1/2] dt-bindings: clock: Introduce QCOM RPMh clock bindings




Add RPMh clock device bindings for Qualcomm Technology Inc's SoCs. These
devices would be used for communicating resource state requests to control
the clocks managed by RPMh.

+Qualcomm Technologies, Inc. RPMh Clocks
+-------------------------------------------------------
+
+Resource Power Manager Hardened (RPMh) manages shared resources on
+some Qualcomm Technologies Inc. SoCs. It accepts clock requests from
+other hardware subsystems via RSC to control clocks.
+
+Required properties :
+- compatible : shall contain "qcom,sdm845-rpmh-clk"
+
+- #clock-cells : must contain 1
+
+Example :
+
+#include <dt-bindings/clock/qcom,rpmh.h>
+
+	&apps_rsc {
+		rpmhcc: clock-controller {
+			compatible = "qcom,sdm845-rpmh-clk";
+			#clock-cells = <1>;
+		};
+	};
