Just wondering, wouldn't it be better instead of adding those defines to define a macro like #define VIDEO_BUS_TO_MBUS(x) V4L2_MBUS_ ## x = VIDEO_BUS_ ## x and then do enum v4l2_mbus_pixelcode { VIDEO_BUS_TO_MBUS(FIXED), VIDEO_BUS_TO_MBUS(RGB444_2X8_PADHI_BE), ... }; ? I'm not very strong on this, I just think an enum is nicer than a bunch of defines and this way copy-paste errors are less likely, but if you or others strongly disagree - I won't insist :) Whether or not you decide to accept this proposal you have my Acked-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Thanks Guennadi > --- > include/uapi/linux/Kbuild | 1 + > include/uapi/linux/v4l2-mediabus.h | 183 ++++++++++++++-------------------- > include/uapi/linux/video-bus-format.h | 127 +++++++++++++++++++++++ > 3 files changed, 205 insertions(+), 106 deletions(-) > create mode 100644 include/uapi/linux/video-bus-format.h > > diff --git a/include/uapi/linux/Kbuild b/include/uapi/linux/Kbuild > index 24e9033..371874b 100644 > --- a/include/uapi/linux/Kbuild > +++ b/include/uapi/linux/Kbuild > @@ -408,6 +408,7 @@ header-y += veth.h > header-y += vfio.h > header-y += vhost.h > header-y += videodev2.h > +header-y += video-bus-format.h > header-y += virtio_9p.h > header-y += virtio_balloon.h > header-y += virtio_blk.h > diff --git a/include/uapi/linux/v4l2-mediabus.h b/include/uapi/linux/v4l2-mediabus.h > index 1445e85..8c31f11 100644 > --- a/include/uapi/linux/v4l2-mediabus.h > +++ b/include/uapi/linux/v4l2-mediabus.h > @@ -13,119 +13,90 @@ > > #include <linux/types.h> > #include <linux/videodev2.h> > +#include <linux/video-bus-format.h> > > -/* > - * These pixel codes uniquely identify data formats on the media bus.

I'm not very strong on this, I just think an enum is nicer than a bunch > of defines and this way copy-paste errors are less likely, but if you or > others strongly disagree - I won't insist :) I'd say it might be a good solution if we enforce new users (including user space users) to use video_bus_format enum values instead of v4l2_mbus_pixelcode ones. But if we keep adding new values to this enum I'd say this approach is less readable than having the full names (V4L2_MBUS_XXX) expressed, because users will still have to use those full names. Anyway, I can still replace this macro list by an enum: enum v4l2_mbus_pixelcode { V4L2_MBUS_FIXED = VIDEO_BUS_FIXED, V4L2_MBUS_RGB444_2X8_PADHI_BE = VIDEO_BUS_RGB444_2X8_PADHI_BE, ... }; Best Regards, Boris

Rename mediabus formats and move the enum into a separate header file so that it can be used by DRM/KMS subsystem without any reference to the V4L2 subsystem. Old V4L2_MBUS_FMT_ definitions are now macros that points to VIDEO_BUS_FMT_ definitions.
