[media] cec.h: merge cec-edid.h into cec.h

2017-04-19T09:53:18+00:00

Drop the separate cec-edid.h header and merge it into cec.h.

There was really no need to have a separate header for this.

[media] cec: Kconfig cleanup

2017-04-19T09:50:52+00:00

The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

[media] v4l: Add metadata buffer type and format

2017-04-15T01:37:02+00:00

The metadata buffer type is used to transfer metadata between userspace
and kernelspace through a V4L2 buffers queue. It comes with a new
metadata capture capability and format description.

[media] media: add CEC notifier support

2017-04-10T15:48:28+00:00

Add support for CEC notifiers, which is used to convey CEC physical address
information from video drivers to their CEC counterpart driver(s).

Based on an earlier version from Russell King:

https://patchwork.kernel.org/patch/9277043/

The cec_notifier is a reference counted object containing the CEC physical address
state of a video device.

When a new notifier is registered the current state will be reported to
that notifier at registration time.

Changeset 446aba663b82 ("[media] tveeprom: get rid of unused arg
on tveeprom_hauppauge_analog()") removed the now unused I2C adapter
struct from struct tveeprom. Remove the corresponding kernel-doc
tag.

[media] vb2: convert vb2_vmarea_handler refcount from atomic_t to refcount_t

2017-04-05T18:31:57+00:00

Use refcount_t to manage the refcount to the memory type specific buffer
videobuf2 buffer implementations. refcount_t is better suitable for the
purpose than atomic_t.

[media] cec: Add cec_get_drvdata()

2017-04-05T18:17:58+00:00

Add a helper function to get driver private data from CEC
adapter. This helps the readability a little bit and allows
to change the 'priv' field name to something else without
needing to touch all drivers.
