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,rpmh-clk-sdm845"

We have a chance to fix this to Rob's liking, so please make this
"qcom,sdm845-rpmh-clock" (or maybe "qcom,sdm845-rpmhcc"?)

I would fix it to "qcom,sdm845-rpmh-clk".


+
+- #clock-cells : must contain 1
+
+Example :
+
+#include <dt-bindings/clock/qcom,rpmh.h>
+
+ &apps_rsc {
+ rpmh: clock-controller {

I believe the clock-controller, the power-domain and the bus-scaler are
equal contenders of the label "rpmh", so please make it more specific.
How about "rpmhcc" to mimic previous platforms?


Would update it "rpmhcc".

+ compatible = "qcom,rpmh-clk-sdm845";
+ #clock-cells = <1>;
+ };
+ };

Regards,
Bjorn
