Qualcomm Technologies, Inc. CDSP Request Manager driver

CDSP Request Manager driver implements an rpmsg interface with

CDSP subsystem to serve L3 frequency and CPU QoS requests from CDSP.

It also interacts with NPU, Camera modules for Cx iPeak mitigations and

thermal module via CDSP/HVX cooling devices for thermal mitigation of

CDSP core.

Required properties:

- compatible: Must be "qcom,msm-cdsprm-rpmsg"

- qcom,glink-channels: Glink channel for communication with CDSP

- qcom,intents: A list of <number of intents, size of each intent>

- qcom,msm-cdsp-rm: A sub-device node to define CDSPM RM, Cx iPeak mitigation

		driver and CDSP core thermal cooling device

	Required properties:

	- compatible: Must be "qcom,msm-cdsp-rm"

	- qcom,qos-latency-us: pm_qos latency vote to be applied on CDSP request in

				micro seconds

	- qcom,qos-maxhold-ms: Maximum hold time for pm_qos latency vote from CDSP

				in milli seconds

	- qcom,compute-cx-limit-en: To enable CX ipeak limit management for compute

				subsystem

	- qcom,compute-priority-mode: when Cx iPeak mitigation is enabled,

				this field sets desired compute priority mode

				for AIX and HVX concurrency cases based on

				following values, where in HVX and NPU cores,

				if required, are throttled in concurrency based

				on the selected priority mode

				1 : HVX_MAX - Allows HVX to run at maximum possible

						frequency during concurrency with NPU

				2 : AIX_MAX - Allows NPU to run at maximum possible

						frequency during concurrency with HVX

				3 : HVX_OVER_AIX - Allows HVX to run at a higher

						frequency than NPU during concurrency

				4 : AIX_OVER_HVX - Allows NPU to run at a higher

						frequency than HVX during concurrency

	- #cooling-cells: Number of cooling cells for CDSP cooling device based on

			CDSP Q6 core clock throttling

- qcom,msm-hvx-rm: A sub-device node to define HVX based thermal cooling device

	Required properties:

	- compatible: Must be "qcom,msm-hvx-rm"

	- #cooling-cells: Number of cooling cells for CDSP cooling device based on

			HVX hardware throttling

- qcom,cdsp-l3: A sub-device node to define CDSP L3 target device for L3

		clock voting

	Required properties:

	- compatible: Must be "qcom,cdsp-l3"

	- qcom,target-dev: The DT device that corresponds to the CDSP L3

			devfreq-simple-dev
