As per the suggestion of Thierry Reding rename HDMI_AUDIO_CODING_TYPE_EXT_STREAM to HDMI_AUDIO_CODING_TYPE_EXT_CT to be consistent with the CEA-861 spec.

2015-01-27[media] hdmi: added unpack and logging functions for InfoFramesMartin Bugge1-0/+4
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.

2014-03-13drm/docs: Include hdmi infoframe helper referenceDaniel Vetter1-0/+12
Thierry created such nice kerneldocs, it's a shame we've left them lingering! For the fun of it also add a bit of kerneldoc to the header so that we can also include that.

2013-08-30video/hdmi: Use hdmi_vendor_infoframe for the HDMI specific infoframeLespiau, Damien1-7/+8
We just got rid of the version of hdmi_vendor_infoframe that had a byte array for anyone to poke at. It's now time to shuffle around the naming of hdmi_hdmi_infoframe to make hdmi_vendor_infoframe become the HDMI vendor specific structure.

2013-08-30video/hdmi: Hook the HDMI vendor infoframe with the generic _pack()Lespiau, Damien1-12/+12
With this last bit, hdmi_infoframe_pack() is now able to pack any infoframe we support. At the same time, because it's impractical to make two commits out of this, we get rid of the version that encourages the open coding of the vendor infoframe packing. We can do so because the only user of this API has been ported in: Author: Damien Lespiau <[email protected]> Date: Mon Aug 12 18:08:37 2013 +0100 gpu: host1x: Port the HDMI vendor infoframe code the common helpers v2: Change oui to be an unsigned int (Ville Syrjälä) Signed-off-by: Damien Lespiau <[email protected]> Reviewed-by: Ville Syrjälä <[email protected]> Reviewed-by: Thierry Reding <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
2013-08-30drm/edid: Move HDMI_IDENTIFIER to hdmi.hLespiau, Damien1-0/+1
We'll need the HDMI OUI for the HDMI vendor infoframe data, so let's move the DRM one to hdmi.h, might as well use the hdmi header to store some hdmi defines. (Note that, in fact, infoframes are part of the CEA-861 standard, and only the HDMI vendor specific infoframe is special to HDMI, but details..)

Provide the same programming model than the other infoframe types.

To set the active aspect ratio value in the AVI infoframe today, you not only have to set the active_aspect field, but also the active_info_valid bit.
