MEDIA_BUS_TYPE_BT601 is thus likely not a good name. I haven't been able to find a standard for parallel camera interfaces that would be a good match here. On the display side there's MIPI DPI, but on the camera side it seems things have evolved quite organically. I may have missed something though. > --- > include/dt-bindings/media/video-interfaces.h | 16 ++++++++++++++++ > 1 file changed, 16 insertions(+) > create mode 100644 include/dt-bindings/media/video-interfaces.h > > diff --git a/include/dt-bindings/media/video-interfaces.h b/include/dt-bindings/media/video-interfaces.h > new file mode 100644 > index 000000000000..4c3810edff4c > --- /dev/null > +++ b/include/dt-bindings/media/video-interfaces.h > @@ -0,0 +1,16 @@ > +/* SPDX-License-Identifier: (GPL-2.0-only OR MIT) */ > +/* > + * Copyright (C) 2022 Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> > + */ > + > +#ifndef __DT_BINDINGS_MEDIA_VIDEO_INTERFACES_H__ > +#define __DT_BINDINGS_MEDIA_VIDEO_INTERFACES_H__ > + > +#define MEDIA_BUS_TYPE_CSI2_CPHY 1 > +#define MEDIA_BUS_TYPE_CSI1 2 > +#define MEDIA_BUS_TYPE_CCP2 3 > +#define MEDIA_BUS_TYPE_CSI2_DPHY 4 > +#define MEDIA_BUS_TYPE_BT601 5 > +#define MEDIA_BUS_TYPE_BT656 6 > + > +#endif /* __DT_BINDINGS_MEDIA_VIDEO_INTERFACES_H__ */ -- Regards, Laurent Pinchart
