Add ADE display controller binding doc.
Add DesignWare DSI Host Controller v1.20a binding doc.
Signed-off-by: Xinliang Liu <xinliang.liu@xxxxxxxxxx>
v3:
- Make ade as the drm master node.
- Use assigned-clocks to set clock rate.
- Use ports to connect display relavant nodes.
v2:
- Move dt binding docs to bindings/display/hisilicon directory.

+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.
+
+Required properties:
+- compatible: value should be "hisilicon,hi6220-dsi".
+- reg: physical base address and length of the 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, and output port connected to external HDMI
+ endpoint. See Documentation/devicetree/bindings/graph.txt for more device
+ graph info.
+
+A example of HiKey board hi6220 SoC and board specific DT entry:
+Example:
+
+SoC specific:
+ dsi: dsi@0xf4107800 {
+ compatible = "hisilicon,hi6220-dsi";
+ reg = <0x0 0xf4107800 0x0 0x100>;

+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 controller's registers.
+- reg-names: name of physical base.
+- interrupt: the interrupt number.
+- clocks: the clocks needed.
+- clock-names: the name of the clocks.
+- assigned-clocks: clocks to be assigned rate.
+- assigned-clock-rates: clock rates which are assigned to assigned-clocks.
+- port: the output port. This contains one endpoint subnode, with its
+ remote-endpoint set to the phandle of the connected DSI endpoint.
+ See Documentation/devicetree/bindings/graph.txt for more device graph info.
+
+Optional properties:
+- dma-coherent: Present if dma operations are coherent.
+
+
+A example of HiKey board hi6220 SoC specific DT entry:
+Example:
