+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.txt.
+
+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.txt.
+
+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-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 and mt8173.
+- 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 and mt8173.
+- larb: Should contain a phandle pointing to the local arbiter device as defined
+  in Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
+- iommus: Should point to the respective IOMMU block with master port as
+  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
+  for details.
