1Mediatek DSI Device 2=================== 3 4The Mediatek DSI function block is a sink of the display subsystem and can 5drive up to 4-lane MIPI DSI output. Two DSIs can be synchronized for dual- 6channel output. 7 8Required properties: 9- compatible: "mediatek,<chip>-dsi" 10- the supported chips are mt2701, mt7623, mt8167, mt8173 and mt8183. 11- reg: Physical base address and length of the controller's registers 12- interrupts: The interrupt signal from the function block. 13- clocks: device clocks 14 See Documentation/devicetree/bindings/clock/clock-bindings.txt for details. 15- clock-names: must contain "engine", "digital", and "hs" 16- phys: phandle link to the MIPI D-PHY controller. 17- phy-names: must contain "dphy" 18- port: Output port node with endpoint definitions as described in 19 Documentation/devicetree/bindings/graph.txt. This port should be connected 20 to the input port of an attached DSI panel or DSI-to-eDP encoder chip. 21 22Optional properties: 23- resets: list of phandle + reset specifier pair, as described in [1]. 24 25[1] Documentation/devicetree/bindings/reset/reset.txt 26 27MIPI TX Configuration Module 28============================ 29 30See phy/mediatek,dsi-phy.yaml 31 32Example: 33 34mipi_tx0: mipi-dphy@10215000 { 35 compatible = "mediatek,mt8173-mipi-tx"; 36 reg = <0 0x10215000 0 0x1000>; 37 clocks = <&clk26m>; 38 clock-output-names = "mipi_tx0_pll"; 39 #clock-cells = <0>; 40 #phy-cells = <0>; 41 drive-strength-microamp = <4600>; 42 nvmem-cells= <&mipi_tx_calibration>; 43 nvmem-cell-names = "calibration-data"; 44}; 45 46dsi0: dsi@1401b000 { 47 compatible = "mediatek,mt8173-dsi"; 48 reg = <0 0x1401b000 0 0x1000>; 49 interrupts = <GIC_SPI 192 IRQ_TYPE_LEVEL_LOW>; 50 clocks = <&mmsys MM_DSI0_ENGINE>, <&mmsys MM_DSI0_DIGITAL>, 51 <&mipi_tx0>; 52 clock-names = "engine", "digital", "hs"; 53 resets = <&mmsys MT8173_MMSYS_SW0_RST_B_DISP_DSI0>; 54 phys = <&mipi_tx0>; 55 phy-names = "dphy"; 56 57 port { 58 dsi0_out: endpoint { 59 remote-endpoint = <&panel_in>; 60 }; 61 }; 62};
