+The Visionox RM69299 is a generic display driver, currently only configured +for use in the 1080p display on the Qualcomm SC7180 MTP board.
+Required properties: +- compatible: should be "visionox,rm69299-1080p-display" +- vdda-supply: phandle of the regulator that provides the supply voltage
- Power IC supply
+- vdd3p3-supply: phandle of the regulator that provides the supply voltage
- Power IC supply
+- reset-gpios: phandle of gpio for reset line
- This should be 8mA, gpio can be configured using mux, pinctrl, pinctrl-names
- (active low)
+- mode-gpios: phandle of the gpio for choosing the mode of the display
- for single DSI
+- ports: This device has one video port driven by one DSI. Their connections
- are modeled using the OF graph bindings specified in
- Documentation/devicetree/bindings/graph.txt.
- port@0: DSI input port driven by master DSI
+Example:
dsi@ae94000 {panel@0 {compatible = "visionox,rm69299-1080p-display";reg = <0>;vdda-supply = <&src_pp1800_l8c>;vdd3p3-supply = <&src_pp2800_l18a>;pinctrl-names = "default", "suspend";pinctrl-0 = <&disp_pins_default>;pinctrl-1 = <&disp_pins_default>;reset-gpios = <&pm6150l_gpios 3 0>;display-timings {timing0: timing-0 {/* originally* 268316160 Mhz,* but value below fits* better w/ downstream*/clock-frequency = <158695680>;hactive = <1080>;vactive = <2248>;hfront-porch = <26>;hback-porch = <36>;hsync-len = <2>;vfront-porch = <56>;vback-porch = <4>;vsync-len = <4>;};
why do we specify timings in dt? Would the panel use different timings on a different board?
