Resource Power Manager(RPM)
RPM is a dedicated hardware engine for managing shared SoC resources,
which includes buses, clocks, power rails, etc. The goal of RPM is
to achieve the maximum power savings while satisfying the SoC's
operational and performance requirements. RPM accepts resource
requests from multiple RPM masters. It arbitrates and aggregates
the requests, and configures the shared resources. The RPM masters
are the application processor, the modem processor, as well as hardware
accelerators. The RPM driver communicates with the hardware engine using
SMD.
The devicetree representation of the RPM block should be:
Required properties
- compatible: "qcom,rpm-smd"
- rpm-channel-name: The string corresponding to the channel name of the
peripheral subsystem. Required for both smd and
glink transports.
- rpm-channel-type: The interal SMD edge for this subsystem found in
<soc/qcom/smd.h>
- interrupts: The IRQ used by remote processor to inform APSS about
reception of response message packet.
Optional properties
- rpm-standalone: Allow RPM driver to run in standalone mode irrespective of RPM
channel presence.
- reg: Contains the memory address at which rpm messaging format version is
stored. If this field is not present, the target only supports v0 format.
Example:
qcom,rpm-smd {
compatible = "qcom,rpm-smd";
interrupts = <GIC_SPI 194 IRQ_TYPE_EDGE_RISING>;
qcom,rpm-channel-name = "rpm_requests";
qcom,rpm-channel-type = 15; /* APPS_RPM_SMD */
}

* RPM Stats
RPM maintains a counter of the masters i.e APPS, MPPS etc
number of times the SoC entered a deeper sleep mode involving
lowering or powering down the backbone rails - Cx and Mx and
the oscillator clock, XO.
PROPERTIES
- compatible:
Usage: required
Value type: <string>
Definition: Should be "qcom,rpm-master-stats".
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: The address on the RPM RAM from where the stats are read
should be provided as "phys_addr_base". The offset
from which the stats are available should be provided as
"offset_addr".
- reg-names:
Usage: required
Value type: <prop-encoded-array>
Definition: Provides labels for the reg property.
- qcom,masters:
Usage: required
Value tye: <string list>
Defination: Provides the masters list.
qcom,master-offset:
Usage: required
Value tye: <prop-encoded-array>
Defination: Provides the masters list
EXAMPLE:
qcom,rpm-master-stats@60150 {

reg = <0x45f0150 0x5000>;
qcom,masters = "APSS", "MPSS", "ADSP", "CDSP", "TZ";
qcom,master-stats-version = <2>;
qcom,master-offset = <4096>;
