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: contains APB clock phandle + clock-specifier pair.
|
|
- clock-names: should be "pclk".
|
|
- 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.
