+
+This adds initial support for clocks controlled by the Resource
+Power Manager (RPM) processor on some Qualcomm SoCs, which use
+the qcom_smd_rpm driver to communicate with RPM.
+Such platforms are msm8916, apq8084 and msm8974.
+
+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.
+
+This driver is based on the codeaurora.org driver:
+https://www.codeaurora.org/cgit/quic/la/kernel/msm-3.10/tree/drivers/clk/qcom/clock-rpm.c

++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"
++
++- #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>;
++ };
++ };
++ };
++ };

+Subject: clk: qcom: Add support for RPM Clocks
+
+This adds initial support for clocks controlled by the Resource
+Power Manager (RPM) processor on some Qualcomm SoCs, which use
+the qcom_rpm driver to communicate with RPM.
+Such platforms are apq8064 and msm8960.

++ The RPM (Resource Power Manager) is a dedicated hardware engine for

-This adds initial support for clocks controlled by the Resource
-Power Manager (RPM) processor on some Qualcomm SoCs, which use
-the qcom_smd_rpm driver to communicate with RPM.
-Such platforms are msm8916, apq8084 and msm8974.
-
-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.
-
-This driver is based on the codeaurora.org driver:
-https://www.codeaurora.org/cgit/quic/la/kernel/msm-3.10/tree/drivers/clk/qcom/clock-rpm.c

-+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"
-+
-+- #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";

-This adds initial support for clocks controlled by the Resource
-Power Manager (RPM) processor on some Qualcomm SoCs, which use
-the qcom_rpm driver to communicate with RPM.
-Such platforms are ipq806x and msm8960.
