-Mediatek display subsystem
-==========================
-
-The Mediatek display subsystem consists of various DISP function blocks in the
-MMSYS register space. The connections between them can be configured by output
-and input selectors in the MMSYS_CONFIG register space. Pixel clock and start
-of frame signal are distributed to the other function blocks by a DISP_MUTEX
-function block.
-
-All DISP device tree nodes must be siblings to the central MMSYS_CONFIG node.
-For a description of the MMSYS_CONFIG binding, see
-Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml.
-
-DISP function blocks
-====================
-
-A display stream starts at a source function block that reads pixel data from
-memory and ends with a sink function block that drives pixels on a display
-interface, or writes pixels back to memory. All DISP function blocks have
-their own register space, interrupt, and clock gate. The blocks that can
-access memory additionally have to list the IOMMU and local arbiter they are
-connected to.
-
-For a description of the display interface sink function blocks, see
-Documentation/devicetree/bindings/display/mediatek/mediatek,dsi.txt and
-Documentation/devicetree/bindings/display/mediatek/mediatek,dpi.yaml.
-
-Required properties (all function blocks):
-- compatible: "mediatek,<chip>-disp-<function>", one of
-	"mediatek,<chip>-disp-ovl"   		- overlay (4 layers, blending, csc)
-	"mediatek,<chip>-disp-ovl-2l"           - overlay (2 layers, blending, csc)
-	"mediatek,<chip>-disp-rdma"  		- read DMA / line buffer
-	"mediatek,<chip>-disp-wdma"  		- write DMA
-	"mediatek,<chip>-disp-ccorr"            - color correction
-	"mediatek,<chip>-disp-color" 		- color processor
-	"mediatek,<chip>-disp-dither"           - dither
-	"mediatek,<chip>-disp-aal"   		- adaptive ambient light controller
-	"mediatek,<chip>-disp-gamma" 		- gamma correction
-	"mediatek,<chip>-disp-merge" 		- merge streams from two RDMA sources
-	"mediatek,<chip>-disp-postmask" 	- control round corner for display frame
-	"mediatek,<chip>-disp-split" 		- split stream to two encoders
-	"mediatek,<chip>-disp-ufoe"  		- data compression engine
-	"mediatek,<chip>-dsi"        		- DSI controller, see mediatek,dsi.txt
-	"mediatek,<chip>-dpi"        		- DPI controller, see mediatek,dpi.txt
-	"mediatek,<chip>-disp-mutex" 		- display mutex
-	"mediatek,<chip>-disp-od"    		- overdrive
-  the supported chips are mt2701, mt7623, mt2712, mt8167, mt8173, mt8183 and mt8192.
-- reg: Physical base address and length of the function block register space
-- interrupts: The interrupt signal from the function block (required, except for
-  merge and split function blocks).
-- clocks: device clocks
-  See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
-  For most function blocks this is just a single clock input. Only the DSI and
-  DPI controller nodes have multiple clock inputs. These are documented in
-  mediatek,dsi.txt and mediatek,dpi.txt, respectively.
-  An exception is that the mt8183 mutex is always free running with no clocks property.
-
-Required properties (DMA function blocks):
-- compatible: Should be one of
-	"mediatek,<chip>-disp-ovl"
-	"mediatek,<chip>-disp-rdma"
-	"mediatek,<chip>-disp-wdma"
-  the supported chips are mt2701, mt8167 and mt8173.
-- larb: Should contain a phandle pointing to the local arbiter device as defined
-  in Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.yaml
-- iommus: Should point to the respective IOMMU block with master port as
-  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml
-  for details.
-
-Optional properties (RDMA function blocks):
-- mediatek,rdma-fifo-size: rdma fifo size may be different even in same SOC, add this
-  property to the corresponding rdma
-  the value is the Max value which defined in hardware data sheet.
-  mediatek,rdma-fifo-size of mt8173-rdma0 is 8K
-  mediatek,rdma-fifo-size of mt8183-rdma0 is 5K
-  mediatek,rdma-fifo-size of mt8183-rdma1 is 2K
