Then maybe leave all the other properties in this file, as it seems like all MIPI panels use the exact same pin/supplies?

I meant sku176 (since you are adding sku0 with a different panel compatible later). > > Then maybe leave all the other properties in this file, as it seems > like all MIPI panels use the exact same pin/supplies? > > (And add a comment here saying that the compatible needs to be set in > board dts?) > > > + reg = <0>; > > + enable-gpios = <&pio 45 0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&panel_pins_default>; > > + avdd-supply = <&ppvarn_lcd>; > > + avee-supply = <&ppvarp_lcd>; > > + pp1800-supply = <&pp1800_lcd>; > > + status = "okay"; > > + port { > > + panel_in: endpoint { > > + remote-endpoint = <&dsi_out>; > > + }; > > + }; > > + }; > > + > > + ports { > > + port { > > + dsi_out: endpoint { > > + remote-endpoint = <&panel_in>; > > + }; > > + }; > > + }; > > +}; > > + > > &i2c0 { > > pinctrl-names = "default"; > > pinctrl-0 = <&i2c0_pins>; > > @@ -547,6 +577,14 @@ pins_clk { > > }; > > }; > > > > + panel_pins_default: panel_pins_default { > > + panel_reset { > > + pinmux = <PINMUX_GPIO45__FUNC_GPIO45>; > > + output-low; > > + bias-pull-up; > > + }; > > + }; > > + > > pwm0_pin_default: pwm0_pin_default { > > pins1 { > > pinmux = <PINMUX_GPIO176__FUNC_GPIO176>; > > -- > > 2.29.2.729.g45daf8777d-goog > >
