Merge "ARM: dts: msm: Add VTCM details to cdsprm document"

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.

CDSP core. It sends VTCM partitioning information on supported chipsets

to CDSP.

Required properties:

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

- 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

		driver, CDSP core thermal cooling device and CDSP VTCM partitioning

	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

	Optional properties:

	Cx iPeak limit management:

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

				subsystem

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

						frequency than NPU during concurrency

				4 : AIX_OVER_HVX - Allows NPU to run at a higher

						frequency than HVX during concurrency

	VTCM partitioning:

	- qcom,vtcm-paritions: Number of VTCM partitions (maximum 16)

	- qcom,vtcm-partition-info: Specifies the partitions, their sizes and

				flags. Most importantly flags can be used to

				set some partitions as privileged,

				i.e. only available to privileged clients.

				Currently VTCM_FLAG_PRIMARY(0x1), VTCM_FLAG_SECONDARY (0x2)and

				VTCM_FLAG_PRIVILEGED(0x4) are the supported flags per partition

				(only one per partition).

				Size of each partition should be a multiple of 256KB.

				Given 256KB is the minimum VTCM allocation size,

				256K, 1M, 4M are supported page sizes.

				Specifying a 3MB partition will allow maximum of 1MB page (3x).

				Similarly, a 512KB partition will be of 256KB pages (2x).

				PRIMARY and SECONDARY partitions are available to all the clients while

				the PRIMARY partition is used by default. Partition selection is

				controlled by the vtcm-partition-map information.

				There must be only one PRIMARY partition.

				Partitions must be defined with a linear partition index

				starting with 0 till (Number of VTCM partitions - 1).

				VTCM memory will be partitioned in the order provided

				(0 being the first partition).

	- qcom,vtcm-partition-map: Maps application type identifiers to

				partitions. Clients use application type IDs to

				request non-default partitions.

				Application identifier is specified as a value [0 – 31]

				in the device tree. The default application identifier

				will be 0. Application identifier must be unique for each

				partition map. Any unassigned application identifier

				in the set of [0 – 31] will be mapped to the PRIMARY partition

				and will return failure if there is no

				PRIMARY partition configured.

			CDSP Q6 core clock throttling
