1Rockchip RK3288 LVDS interface 2================================ 3 4Required properties: 5- compatible: matching the soc type, one of 6 - "rockchip,rk3288-lvds"; 7 - "rockchip,px30-lvds"; 8 9- reg: physical base address of the controller and length 10 of memory mapped region. 11- clocks: must include clock specifiers corresponding to entries in the 12 clock-names property. 13- clock-names: must contain "pclk_lvds" 14 15- avdd1v0-supply: regulator phandle for 1.0V analog power 16- avdd1v8-supply: regulator phandle for 1.8V analog power 17- avdd3v3-supply: regulator phandle for 3.3V analog power 18 19- rockchip,grf: phandle to the general register files syscon 20- rockchip,output: "rgb", "lvds" or "duallvds", This describes the output interface 21 22- phys: LVDS/DSI DPHY (px30 only) 23- phy-names: name of the PHY, must be "dphy" (px30 only) 24 25Optional properties: 26- pinctrl-names: must contain a "lcdc" entry. 27- pinctrl-0: pin control group to be used for this controller. 28 29Required nodes: 30 31The lvds has two video ports as described by 32 Documentation/devicetree/bindings/media/video-interfaces.txt 33Their connections are modeled using the OF graph bindings specified in 34 Documentation/devicetree/bindings/graph.txt. 35 36- video port 0 for the VOP input, the remote endpoint maybe vopb or vopl 37- video port 1 for either a panel or subsequent encoder 38 39Example: 40 41lvds_panel: lvds-panel { 42 compatible = "auo,b101ean01"; 43 enable-gpios = <&gpio7 21 GPIO_ACTIVE_HIGH>; 44 data-mapping = "jeida-24"; 45 46 ports { 47 panel_in_lvds: endpoint { 48 remote-endpoint = <&lvds_out_panel>; 49 }; 50 }; 51}; 52 53For Rockchip RK3288: 54 55 lvds: lvds@ff96c000 { 56 compatible = "rockchip,rk3288-lvds"; 57 rockchip,grf = <&grf>; 58 reg = <0xff96c000 0x4000>; 59 clocks = <&cru PCLK_LVDS_PHY>; 60 clock-names = "pclk_lvds"; 61 pinctrl-names = "lcdc"; 62 pinctrl-0 = <&lcdc_ctl>; 63 avdd1v0-supply = <&vdd10_lcd>; 64 avdd1v8-supply = <&vcc18_lcd>; 65 avdd3v3-supply = <&vcca_33>; 66 rockchip,output = "rgb"; 67 ports { 68 #address-cells = <1>; 69 #size-cells = <0>; 70 71 lvds_in: port@0 { 72 reg = <0>; 73 74 lvds_in_vopb: endpoint@0 { 75 reg = <0>; 76 remote-endpoint = <&vopb_out_lvds>; 77 }; 78 lvds_in_vopl: endpoint@1 { 79 reg = <1>; 80 remote-endpoint = <&vopl_out_lvds>; 81 }; 82 }; 83 84 lvds_out: port@1 { 85 reg = <1>; 86 87 lvds_out_panel: endpoint { 88 remote-endpoint = <&panel_in_lvds>; 89 }; 90 }; 91 }; 92 };
