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. Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

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