mdss-dsi is the master DSI device which supports multiple DSI host controllers
that are compatible with MIPI display serial interface specification.

DSI Controller:
Required properties:
- compatible:           Should be "qcom,dsi-ctrl-hw-v<version>". Supported
			versions include 1.4 and 2.0.
			eg: qcom,dsi-ctrl-hw-v1.4, qcom,dsi-ctrl-hw-v2.0
			And for dsi phy driver:
			qcom,dsi-phy-v1.0, qcom,dsi-phy-v2.0, qcom,dsi-phy-v3.0,
			qcom,dsi-phy-v4.0
			For display manager driver:
			qcom,dsi-display, qcom,hdmi-display, qcom,dp-display
- reg:                  Base address and length of DSI controller's memory
			mapped regions.
- reg-names:            A list of strings that name the list of regs.
			"dsi_ctrl" - DSI controller memory region.
			"mmss_misc" - MMSS misc memory region.
- cell-index:           Specifies the controller instance.
- clocks:               Clocks required for DSI controller operation.
- clock-names:          Names of the clocks corresponding to handles. Following
			clocks are required:
			"mdp_core_clk"
			"iface_clk"
			"core_mmss_clk"
			"bus_clk"
			"byte_clk"
			"pixel_clk"
			"core_clk"
			"byte_clk_rcg"
			"pixel_clk_rcg"
- gdsc-supply:		phandle to gdsc regulator node.
- vdda-supply:		phandle to vdda regulator node.
- vcca-supply:		phandle to vcca regulator node.
- interrupt-parent	phandle to the interrupt parent device node.
- interrupts:		The interrupt signal from the DSI block.

Bus Scaling Data:
- qcom,msm-bus,name:		String property describing MDSS client.
- qcom,msm-bus,num-cases:	This is the number of bus scaling use cases
				defined in the vectors property. This must be
				set to <2> for MDSS DSI driver where use-case 0
				is used to remove BW votes from the system. Use
				case 1 is used to generate bandwidth requestes
				when sending command packets.
- qcom,msm-bus,num-paths:	This represents number of paths in each bus
				scaling usecase. This value depends on number of
				AXI master ports dedicated to MDSS for
				particular chipset.
- 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.
				DSI driver should always set average bandwidth
				(ab) to 0 and always use instantaneous
				bandwidth(ib) values.

Optional properties:
- label:                  String to describe controller.
- qcom,platform-te-gpio:  Specifies the gpio used for TE.
- qcom,dsi-display-active: Current active display
- qcom,dsi-ctrl: handle to dsi controller device
- qcom,dsi-phy: handle to dsi phy device
- qcom,dsi-manager:       Specifies dsi manager is present
- qcom,display-manager:   Specifies display manager is present
- qcom,<type>-supply-entries:		A node that lists the elements of the supply used by the
					a particular "type" of DSI module. The module "types"
					can be "core", "ctrl", and "phy". Within the same type,
					there can be more than one instance of this binding,
					in which case the entry would be appended with the
					supply entry index.
					e.g. qcom,ctrl-supply-entry@0
					-- qcom,supply-name: name of the supply (vdd/vdda/vddio)
					-- qcom,supply-min-voltage: minimum voltage level (uV)
					-- qcom,supply-max-voltage: maximum voltage level (uV)
					-- qcom,supply-enable-load: load drawn (uA) from enabled supply
					-- qcom,supply-disable-load: load drawn (uA) from disabled supply
					-- qcom,supply-pre-on-sleep: time to sleep (ms) before turning on
					-- qcom,supply-post-on-sleep: time to sleep (ms) after turning on
					-- qcom,supply-pre-off-sleep: time to sleep (ms) before turning off
					-- qcom,supply-post-off-sleep: time to sleep (ms) after turning off
