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
+
+Optional properties :
+- assigned-clk-divs : property should contain a list of divs for each clock in
+ the clk-output-names property. In case divs are not
+ provided the clock rate would be same as parent rate.
+- clk-output-names : a list of strings of clock output signal for the divs to
+ be applied.
+
+Example :
+
+#include <dt-bindings/clock/qcom,rpmh.h>
+
+ &apps_rsc {
+ rpmhcc: clock-controller {
+ compatible = "qcom,sdm845-rpmh-clk";
+ #clock-cells = <1>;
+ assigned-clk-divs = <2 2 2>;
+ clk-output-names = "bi_tcxo", "lnbb_clk2",
+ "lnbb_clk3";
+ };
+ };
