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