[media] media/cec.h: use IS_REACHABLE instead of IS_ENABLED

2017-06-08T19:52:28+00:00

Fix messages like this:

adv7842.c:(.text+0x2edadd): undefined reference to `cec_unregister_adapter'

when CEC_CORE=m but the driver including media/cec.h is built-in. In that case
the static inlines provided in media/cec.h should be used by that driver.

[media] cec: rename MEDIA_CEC_NOTIFIER to CEC_NOTIFIER

2017-06-04T18:23:35+00:00

This config option is strictly speaking independent of the
media subsystem since it can be used by drm as well.

Besides, it looks odd when drivers select CEC_CORE and
MEDIA_CEC_NOTIFIER, that's inconsistent naming.

[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] 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.

[media] cec: pass parent device in register(), not allocate()

2016-11-29T14:07:17+00:00

The cec_allocate_adapter function doesn't need the parent device, only the
cec_register_adapter function needs it.

Drop the cec_devnode parent field, since devnode.dev.parent can be used
instead.

This change makes the framework consistent with other frameworks where the
parent device is not used until the device is registered.

[media] cec: move the CEC framework out of staging and to media

2016-11-16T17:40:20+00:00

The last open issues have been addressed, so it is time to move
this out of staging and into the mainline and to move the public
cec headers to include/uapi/linux.

[media] cec: rename cec_devnode fhs_lock to just lock

2016-08-22T16:09:06+00:00

This lock will be used to protect more than just the fhs list.
So rename it to just 'lock'.

[media] cec: limit the size of the transmit queue

2016-07-19T16:25:32+00:00

The size of the transmit queue was unlimited, which meant that
in non-blocking mode you could flood the CEC adapter with messages
to be transmitted.

Limit this to 18 messages.

Also print the number of pending transmits and the timeout value
in the status debugfs file.
