2019-01-25video/hdmi: Add an enum for HDMI packet typesVille Syrjälä
We'll be wanting to send more than just infoframes over HDMI. So add an enum for other packet types.

2018-10-03video/hdmi: Constify infoframe passed to the pack functionsVille Syrjälä
Let's make the infoframe pack functions usable with a const infoframe structure. This allows us to precompute the infoframe earlier, and still pack it later when we're no longer allowed to modify the structure. So now we end up with a _check()+_pack_only() or _pack() functions depending on whether you want to precompute the infoframes or not. The names aren't great but I was lazy and didn't want to change all the drivers. v2: Deal with exynos churn Actually export the new funcs v3: Fix various documentation fails (Hans) Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Hans Verkuil <hans.verkuil@cisco.com> Cc: linux-media@vger.kernel.org Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180921143332.28970-1-ville.syrjala@linux.intel.com Acked-by: Hans Verkuil <hans.verkuil@cisco.com>

2015-01-27[media] hdmi: added unpack and logging functions for InfoFramesMartin Bugge
When receiving video it is very useful to be able to unpack the InfoFrames. Logging is useful as well, both for transmitters and receivers. Especially when implementing the VIDIOC_LOG_STATUS ioctl (supported by many V4L2 drivers) for a receiver it is important to be able to easily log what the InfoFrame contains. This greatly simplifies debugging.
