Subject: [PATCH] drm/vc4: Refactor mode checking logic
|
|
|
|
Replace drm_encoder_helper_funcs::atomic_check with
|
|
drm_connector_helper_funcs::atomic_check - the former is not called
|
|
during drm_mode_obj_set_property_ioctl(). Set crtc_state->mode_changed
|
|
if TV norm changes even without explicit mode change. This makes things
|
|
like "xrandr --output Composite-1 --set mode PAL-M" work properly.
