+Qualcomm Resource Power Manager (RPM)
|
|
+
|
|
+This driver is used to interface with the Resource Power Manager (RPM) found in
|
|
+various Qualcomm platforms. The RPM allows each component in the system to vote
|
|
+for state of the system resources, such as clocks, regulators and bus
|
|
+frequencies.
|
|
+
|
|
+- compatible:
|
|
+ Usage: required
|
|
+ Value type: <string>
|
|
+ Definition: must be one of:
|
|
+ "qcom,rpm-apq8064"
|
|
+ "qcom,rpm-msm8660"
|
|
+ "qcom,rpm-msm8960"
|
|
+
|
|
+- reg:
|
|
+ Usage: required
|
|
+ Value type: <prop-encoded-array>
|
|
+ Definition: base address and size of the RPM's message ram
|
|
+
|
|
+- interrupts:
|
|
+ Usage: required
|
|
+ Value type: <prop-encoded-array>
|
|
+ Definition: three entries specifying the RPM's:
|
|
+ 1. acknowledgement interrupt
|
|
+ 2. error interrupt
|
|
+ 3. wakeup interrupt
|
|
+
|
|
+- interrupt-names:
|
|
+ Usage: required
|
|
+ Value type: <string-array>
|
|
+ Definition: must be the three strings "ack", "err" and "wakeup", in order
|
|
+
|
|
+- #address-cells:
|
|
+ Usage: required
|
|
+ Value type: <u32>
|
|
+ Definition: must be 1
|
|
+
|
|
+- #size-cells:
|
|
+ Usage: required
|
|
+ Value type: <u32>
|
|
+ Definition: must be 0
|
|
+
|
|
+- qcom,ipc:
|
|
+ Usage: required
|
|
+ Value type: <prop-encoded-array>
|
|
+
|
|
+ Definition: three entries specifying the outgoing ipc bit used for
|
|
+ signaling the RPM:
|
|
+ - phandle to a syscon node representing the apcs registers
|
|
+ - u32 representing offset to the register within the syscon
|
|
+ - u32 representing the ipc bit within the register
