Specifically "rockchip,rk3288-edp" should be "rockchip,rk3288-dp". The typo is pre-existing so I'm not sure you would need to spin this series to fix it, but if you were spinning it anyway it wouldn't hurt to fix. Could also just send out a followon patch to fix this after the series lands... -Doug

No need to respin the whole series just for this typo. It's better to fix it in a separate patch later at this point, especially since this revision of the series looks quite good.

How about s->output_type? I plan to return '-ENODEV' when 'drm_of_encoder_active_endpoint_id' failed to found, but now i found there is a bug. When the first time '.atomic_check' was called, encoder have binded to any crtc, so the 'drm_of_encoder_active_endpoint_id' would be failed. - If we return failure in this case, then '.atomic_check' would be called again, then failed again, dead loop. - If we return zero in this case and set a default output_mode/output_type, then '.atomic_check' would be successes, then 'crtc->enable' function would use that default setting. When framework called the 'atomic_check' again, then 'drm_of_encoder_active_endpoint_id' would return the right value, and 'crtc_state would be set rightly. *But* 'vop->enable' wouldn't take care of those setting, caused it would return directly after detect vop have been enabled. This bug need patches both in connector and crtc driver, need more discuss about this. ;) Thanks, - Yakir >> + >> + switch (dp->data->chip_type) { >> + case RK3399_EDP: >> + /* >> + * For RK3399, VOP Lit must code the out mode to RGB888, >> + * VOP Big must code the out mode to RGB10. >> + */ >> + if (ret) >> + s->output_mode = ROCKCHIP_OUT_MODE_P888; >> + else >> + s->output_mode = ROCKCHIP_OUT_MODE_AAAA; >> + break; >> + >> + default: >> + s->output_mode = ROCKCHIP_OUT_MODE_AAAA; >> + break; >> + } >> + > This chunk seems overly complicated.
