I suspect not, and I would suspect that you don't need it on Apalis either, so I think a better patch would just remove it from Apalis as well. > diff --git a/arch/arm/boot/dts/tegra30-colibri.dtsi b/arch/arm/boot/dts/tegra30-colibri.dtsi > index c4ed1be..5f7f4a0 100644 > --- a/arch/arm/boot/dts/tegra30-colibri.dtsi > +++ b/arch/arm/boot/dts/tegra30-colibri.dtsi > @@ -3,7 +3,7 @@ > > /* > * Toradex Colibri T30 Device Tree > - * Compatible for Revisions 1.1B/1.1C/1.1D > + * Compatible for Revisions V1.1B, V1.1C, V1.1D, V1.1E; IT: V1.1A > */ > / { > model = "Toradex Colibri T30"; > @@ -18,9 +18,9 @@ > vdd-supply = <&sys_3v3_reg>; > pll-supply = <&vio_reg>; > > + nvidia,ddc-i2c-bus = <&hdmiddc>; > nvidia,hpd-gpio = > <&gpio TEGRA_GPIO(N, 7) GPIO_ACTIVE_HIGH>; > - nvidia,ddc-i2c-bus = <&hdmiddc>; > }; > }; There's too many changes crammed into this commit for my taste. Can you please separate these out into smaller commits and resend? Thierry
