-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>;
- };
- };
- };
- };
