Why we have those defined in Haikou as well downstream is because we do not have CEC routed on Haikou, but it is exposed by Tiger on Q7 connector, so basically, the point is the pinctrl-0 in Haikou is a subset of the one in Tiger. So please have the following in rk3588-tiger.dtsi as well: pinctrl-0 = <&hdmim1_tx0_cec &hdmim0_tx0_hpd &hdmim1_tx0_scl &hdmim1_tx0_sda>; It'd be nice to have HDMI audio as well, but one thing after the other I guess :) > + status = "okay"; > +}; > + > +&hdmi0_in { BTW, I'm not very happy with this naming. There is an HDMI-RX controller on RK3588 as well, which is routed on Tiger, so this will be unnecessarily confusing: "which one REALLY is the HDMI input". Maybe hdmitx0_in would have made more sense. Anyway, I'm too late to the party :) Cheers, Quentin
