| 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-msm8916", "qcom,rpmcc" | |
| "qcom,rpmcc-msm8974", "qcom,rpmcc" | |
| "qcom,rpmcc-apq8064", "qcom,rpmcc" | |
| - #clock-cells : shall contain 1 | |
| 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>; | |
| }; | |
| }; | |
| }; | |
| }; |
