I suppose that means the default pinctrl should be dropped? Or maybe this use case is the outlier.

Or maybe this > use case is the outlier. Up to Heiko? Interesting question. Right now it looks like Gru is the only one using spdif in that way, so I'd think dropping the pinctrl here is the "saner" option at this time ;-) I guess we can reevaluate if this becomes more widespread > > Fixes: b18c6c3c7768 ("ASoC: rockchip: cdn-dp sound output use spdif") > > Signed-off-by: Brian Norris <briannorris@chromium.org> > > Reviewed-by: Chen-Yu Tsai <wenst@chromium.org> >

Commit b18c6c3c7768 ("ASoC: rockchip: cdn-dp sound output use spdif") switched the platform to SPDIF, but we didn't fix up the device tree. Drop the pinctrl settings, because the 'spdif_bus' pins are either: * unused (on kevin, bob), so the settings is ~harmless * used by a different function (on scarlet), which causes probe failures (!!)
