Merge "drm/msm: Add snapshot of SDE and supporting drivers" into msm-next

Optional properties:

- qcom,dsi-phy-regulator-ldo-mode: Boolean value indicating if the LDO mode PHY

  regulator is wanted.

- qcom,mdss-mdp-transfer-time-us:	Specifies the dsi transfer time for command mode

					panels in microseconds. Driver uses this number to adjust

					the clock rate according to the expected transfer time.

					Increasing this value would slow down the mdp processing

					and can result in slower performance.

					Decreasing this value can speed up the mdp processing,

					but this can also impact power consumption.

					As a rule this time should not be higher than the time

					that would be expected with the processing at the

					dsi link rate since anyways this would be the maximum

					transfer time that could be achieved.

					If ping pong split is enabled, this time should not be higher

					than two times the dsi link rate time.

					If the property is not specified, then the default value is 14000 us.

Qualcomm Technologies, Inc. SDE RSC

Snapdragon Display Engine implements display rsc to driver

display core to different modes for power saving

Required properties

- compatible:			Must be "qcom,sde-rsc"

- reg:				Offset and length of the register set for

				the device.

- reg-names:			Names to refer to register sets related

				to this device

Optional properties:

- clocks:			List of phandles for clock device nodes

				needed by the device.

- clock-names:			List of clock names needed by the device.

- vdd-supply:			phandle for vdd regulator device node.

- qcom,sde-rsc-version:		U32 property represents the rsc version. It helps to

				select correct sequence for sde rsc based on version.

- qcom,sde-dram-channels:	U32 property represents the number of channels in the

				Bus memory controller.

- qcom,sde-num-nrt-paths:	U32 property represents the number of non-realtime

				paths in each Bus Scaling Usecase. This value depends on

				number of AXI ports that are dedicated to non-realtime VBIF

				for particular chipset.

				These paths must be defined after rt-paths in

				"qcom,msm-bus,vectors-KBps" vector request.

Bus Scaling Subnodes:

- qcom,sde-data-bus:		Property to provide Bus scaling for data bus access for

				sde blocks.

- qcom,sde-llcc-bus:		Property to provide Bus scaling for data bus access for

				mnoc to llcc.

- qcom,sde-ebi-bus:		Property to provide Bus scaling for data bus access for

				llcc to ebi.

Bus Scaling Data:

- qcom,msm-bus,name:		String property describing client name.

- qcom,msm-bus,active-only:	Boolean context flag for requests in active or

				dual (active & sleep) contex

- qcom,msm-bus,num-cases:	This is the number of Bus Scaling use cases

				defined in the vectors property.

- qcom,msm-bus,num-paths:	This represents the number of paths in each

				Bus Scaling Usecase.

- qcom,msm-bus,vectors-KBps:	* A series of 4 cell properties, with a format

				of (src, dst, ab, ib) which is defined at

				Documentation/devicetree/bindings/arm/msm/msm_bus.txt

				* Current values of src & dst are defined at

				include/linux/msm-bus-board.h
