Raydium RM67171 OLED LCD panel with MIPI-DSI protocol
Required properties:
- compatible: "raydium,rm67191"
- reg: virtual channel for MIPI-DSI protocol
must be <0>
- dsi-lanes: number of DSI lanes to be used
must be <3> or <4>
- port: input port node with endpoint definition as
defined in Documentation/devicetree/bindings/graph.txt;
the input port should be connected to a MIPI-DSI device
driver
Optional properties:
- reset-gpios: a GPIO spec for the RST_B GPIO pin
- v3p3-supply: phandle to 3.3V regulator that powers the VDD_3V3 pin
- v1p8-supply: phandle to 1.8V regulator that powers the VDD_1V8 pin
- width-mm: see panel-common.txt
- height-mm: see panel-common.txt
- video-mode: 0 - burst-mode
1 - non-burst with sync event
2 - non-burst with sync pulse
Example:
panel@0 {
compatible = "raydium,rm67191";
reg = <0>;
pinctrl-0 = <&pinctrl_mipi_dsi_0_1_en>;
pinctrl-names = "default";
reset-gpios = <&gpio1 7 GPIO_ACTIVE_LOW>;
dsi-lanes = <4>;
width-mm = <68>;
height-mm = <121>;
port {
panel_in: endpoint {
remote-endpoint = <&mipi_out>;
};
};
};
