Pushed to drm-misc-next. PS. I do wonder a bit if we should consider a more economical way to track this stuff. Not really sure how many bits we can realistically expect to be set in these bitmasks... > --- > include/drm/drm_connector.h | 16 ++++++++-------- > 1 file changed, 8 insertions(+), 8 deletions(-) > > diff --git a/include/drm/drm_connector.h b/include/drm/drm_connector.h > index 5f8c3389d46f..17b728d9c73d 100644 > --- a/include/drm/drm_connector.h > +++ b/include/drm/drm_connector.h > @@ -188,19 +188,19 @@ struct drm_hdmi_info { > > /** > * @y420_vdb_modes: bitmap of modes which can support ycbcr420 > - * output only (not normal RGB/YCBCR444/422 outputs).

CEA-861-G adds modes up to 219, so increase the size of the maps in preparation for adding the new modes to drm_edid.c. Signed-off-by: Thomas Anderson <thomasanderson@google.com> --- include/drm/drm_connector.h | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-)
