Pull drm updates from Dave Airlie:
 "Here's the main drm pull request for 4.7, it's been a busy one, and
  I've been a bit more distracted in real life this merge window.  Lots
  more ARM drivers, not sure if it'll ever end.  I think I've at least
  one more coming the next merge window.

  But changes are all over the place, support for AMD Polaris GPUs is in
  here, some missing GM108 support for nouveau (found in some Lenovos),

+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-rdma"  - read DMA / line buffer
+	"mediatek,<chip>-disp-wdma"  - write DMA
+	"mediatek,<chip>-disp-color" - color processor
+	"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
+- 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.
+
+Required properties (DMA function blocks):
+- compatible: Should be one of
+	"mediatek,<chip>-disp-ovl"
+	"mediatek,<chip>-disp-rdma"
+	"mediatek,<chip>-disp-wdma"
+- larb: Should contain a phandle pointing to the local arbiter device as defined
+  in Documentation/devicetree/bindings/soc/mediatek/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.
