+Device-Tree bindings for DesignWare DSI Host Controller v1.20a driver
+
+A DSI Host Controller resides in the middle of display controller and external
+HDMI converter or panel.
+
+Required properties:
+- compatible: value should be "hisilicon,hi6220-dsi".
+- reg: physical base address and length of dsi controller's registers.
+- clocks: the clocks needed.
+- clock-names: the name of the clocks.
+- ports: contains DSI controller input and output sub port.
+  The input port connects to ADE output port with the reg value "0".
+  The output port with the reg value "1", it could connect to panel or
+  any other bridge endpoints.
+  See Documentation/devicetree/bindings/graph.txt for more device graph info.

+Device-Tree bindings for hisilicon ADE display controller driver
+
+ADE (Advanced Display Engine) is the display controller which grab image
+data from memory, do composition, do post image processing, generate RGB
+timing stream and transfer to DSI.
+
+Required properties:
+- compatible: value should be "hisilicon,hi6220-ade".
+- reg: physical base address and length of the ADE controller's registers.
+  Value should be "<0x0 0xf4100000 0x0 0x7800>".
+- reg-names: name of physical base. Value should be "ade_base".
+- hisilicon,noc-syscon: ADE NOC QoS syscon. Value should be "<&medianoc_ade>"
+- resets: The ADE reset controller node. Value should be "<&media_ctrl
+  MEDIA_ADE>".
+- interrupt: the ldi vblank interrupt number used.
+- clocks: the clocks needed. Three clocks are used in ADE driver:
+  ADE core clock, value should be "<&media_ctrl HI6220_ADE_CORE>";
+  ADE pixel clok, value should be "<&media_ctrl HI6220_ADE_PIX_SRC>";
+  media NOC QoS clock, value should be "<&media_ctrl HI6220_CODEC_JPEG>".
+- clock-names: the name of the clocks. Values should be "clk_ade_core",
+  "clk_codec_jpeg" and "clk_ade_pix".
+- assigned-clocks: clocks to be assigned rate.
+- assigned-clock-rates: clock rates which are assigned to assigned-clocks.
+  The rate of <&media_ctrl HI6220_ADE_CORE> could be "360000000" or
+  "180000000";
+  The rate of <&media_ctrl HI6220_CODEC_JPEG> could be less than "1440000000".
+- port: the output port. This contains one endpoint subnode, with its
+  remote-endpoint set to the phandle of the connected DSI input endpoint.
+  See Documentation/devicetree/bindings/graph.txt for more device graph info.
+
+Optional properties:
+- dma-coherent: Present if dma operations are coherent.
