Rockchip RK3288 LVDS interface
|
|
================================
|
|
|
|
Required properties:
|
|
- compatible: matching the soc type, one of
|
|
- "rockchip,rk3288-lvds";
|
|
|
|
- reg: physical base address of the controller and length
|
|
of memory mapped region.
|
|
- clocks: must include clock specifiers corresponding to entries in the
|
|
clock-names property.
|
|
- clock-names: must contain "pclk_lvds"
|
|
|
|
- avdd1v0-supply: regulator phandle for 1.0V analog power
|
|
- avdd1v8-supply: regulator phandle for 1.8V analog power
|
|
- avdd3v3-supply: regulator phandle for 3.3V analog power
|
|
|
|
- rockchip,grf: phandle to the general register files syscon
|
|
- rockchip,output: "rgb", "lvds" or "duallvds", This describes the output interface
|
|
|
|
Optional properties:
|
|
- pinctrl-names: must contain a "lcdc" entry.
|
|
- pinctrl-0: pin control group to be used for this controller.
|
|
|
|
Required nodes:
|
|
|
|
The lvds has two video ports as described by
|
|
Documentation/devicetree/bindings/media/video-interfaces.txt
|
|
Their connections are modeled using the OF graph bindings specified in
|
|
Documentation/devicetree/bindings/graph.txt.
|
|
|
|
- video port 0 for the VOP input, the remote endpoint maybe vopb or vopl
|
|
- video port 1 for either a panel or subsequent encoder
|
|
|
|
the lvds panel described by
|
|
Documentation/devicetree/bindings/display/panel/simple-panel.txt
|
|
|
|
Panel required properties:
|
|
- ports for remote LVDS output
|
|
|
|
Panel optional properties:
|
|
- data-mapping: should be "vesa-24","jeida-24" or "jeida-18".
|
|
This describes decribed by:
|
|
Documentation/devicetree/bindings/display/panel/panel-lvds.txt
|
|
|
|
Example:
|
|
|
|
lvds_panel: lvds-panel {
|
|
compatible = "auo,b101ean01";
|
|
enable-gpios = <&gpio7 21 GPIO_ACTIVE_HIGH>;
|
|
data-mapping = "jeida-24";
|
|
|
|
ports {
|
|
panel_in_lvds: endpoint {
|
|
remote-endpoint = <&lvds_out_panel>;
|
|
};
|
|
};
|
|
};
|
|
|
|
For Rockchip RK3288:
|
|
|
|
lvds: lvds@ff96c000 {
|
|
compatible = "rockchip,rk3288-lvds";
|
|
rockchip,grf = <&grf>;
|
|
reg = <0xff96c000 0x4000>;
|
|
clocks = <&cru PCLK_LVDS_PHY>;
|
|
clock-names = "pclk_lvds";
|
|
pinctrl-names = "lcdc";
|
|
pinctrl-0 = <&lcdc_ctl>;
|
|
avdd1v0-supply = <&vdd10_lcd>;
|
|
avdd1v8-supply = <&vcc18_lcd>;
|
|
avdd3v3-supply = <&vcca_33>;
|
|
rockchip,output = "rgb";
|

lvds_in_vopl: endpoint@1 {
