To drive these Well that and a camera :) Maybe we can provide the "official" name of that adapter so people can easily find it on our product page?

Add the official name in the comment here (maybe a link too?). Aren't we missing a copyright notice here as well (I personally don't care :) )?

The driver inverts the signal and here we invert it as well. c.f. https://lore.kernel.org/linux-rockchip/20221103-upstream-goodix-reset-v3-0-0975809eb183@theobroma-systems.com/ I haven't send a new version yet, I don't really know what should be done there. The main pain point being that this is probably a big patch that spans multiple maintainer trees at once? > + AVDD28-supply = <&vcc2v8_video>; > + VDDIO-supply = <&vcc3v3_baseboard>; > + }; > + > + pca9670: gpio@27 { > + compatible = "nxp,pca9670"; > + reg = <0x27>; > + gpio-controller; > + #gpio-cells = <2>; > + }; > +}; > + > +&mipidcphy0 { > + status = "okay"; > +}; > + > +&pinctrl { > + touch { > + touch_int: touch-int { > + rockchip,pins = <3 RK_PC3 RK_FUNC_GPIO &pcfg_pull_none>; > + }; > + }; > +}; > + > +&pwm0 { > + pinctrl-0 = <&pwm0m1_pins>; > + pinctrl-names = "default"; The other two pin muxes for PWM0 are either: - the pin used for CAN - the pin routed to an internal component (unexposed to Q7) and used as a GPIO so please move the pinctrl to the Tiger SoM DTSI. > + status = "okay"; > +}; > + > +&vp3 { > + #address-cells = <1>; > + #size-cells = <0>; > + Shouldn't those be in the SoC dtsi?
