Qualcomm RPM Clock Controller Binding

------------------------------------------------

The RPM is a dedicated hardware engine for managing the shared

SoC resources in order to keep the lowest power profile. It

communicates with other hardware subsystems via shared memory

and accepts clock requests, aggregates the requests and turns

the clocks on/off or scales them on demand.

Required properties :

- compatible : shall contain only one of the following. The generic

               compatible "qcom,rpmcc" should be also included.

			"qcom,rpmcc-mdm9607", "qcom,rpmcc"

			"qcom,rpmcc-msm8660", "qcom,rpmcc"

			"qcom,rpmcc-apq8060", "qcom,rpmcc"

			"qcom,rpmcc-msm8226", "qcom,rpmcc"

			"qcom,rpmcc-msm8916", "qcom,rpmcc"

			"qcom,rpmcc-msm8936", "qcom,rpmcc"

			"qcom,rpmcc-msm8953", "qcom,rpmcc"

			"qcom,rpmcc-msm8974", "qcom,rpmcc"

			"qcom,rpmcc-msm8976", "qcom,rpmcc"

			"qcom,rpmcc-apq8064", "qcom,rpmcc"

			"qcom,rpmcc-ipq806x", "qcom,rpmcc"

			"qcom,rpmcc-msm8992",·"qcom,rpmcc"

			"qcom,rpmcc-msm8994",·"qcom,rpmcc"

			"qcom,rpmcc-msm8996", "qcom,rpmcc"

			"qcom,rpmcc-msm8998", "qcom,rpmcc"

			"qcom,rpmcc-qcm2290", "qcom,rpmcc"

			"qcom,rpmcc-qcs404", "qcom,rpmcc"

			"qcom,rpmcc-sdm660", "qcom,rpmcc"

			"qcom,rpmcc-sm6115", "qcom,rpmcc"

			"qcom,rpmcc-sm6125", "qcom,rpmcc"

- #clock-cells : shall contain 1

The clock enumerators are defined in <dt-bindings/clock/qcom,rpmcc.h>

and come in pairs: FOO_CLK followed by FOO_A_CLK. The latter clock

is an "active" clock, which means that the consumer only care that the

clock is available when the apps CPU subsystem is active, i.e. not

suspended or in deep idle. If it is important that the clock keeps running

during system suspend, you need to specify the non-active clock, the one

not containing *_A_* in the enumerator name.

Example:

	smd {

		compatible = "qcom,smd";

		rpm {

			interrupts = <0 168 1>;

			qcom,ipc = <&apcs 8 0>;

			qcom,smd-edge = <15>;

			rpm_requests {

				compatible = "qcom,rpm-msm8916";

				qcom,smd-channels = "rpm_requests";

				rpmcc: clock-controller {

					compatible = "qcom,rpmcc-msm8916", "qcom,rpmcc";

					#clock-cells = <1>;

				};

			};

		};

	};
