* [media] cec: move the CEC framework out of staging and to mediaHans Verkuil2016-11-161-411/+0
| | | | | | | | | 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. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

| * [media] cec: improve lockingHans Verkuil2016-08-221-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - The global lock was used in cec_get_device when it should have used the devnode lock. - cec_put_device also took the global lock, but since the release function takes that lock as well this could lead to a deadlock. Just don't take the lock here since there is no reason for it. - cec_devnode_register() should take the global lock when clearing the bit in the global bitmap. - In cec_devnode_unregister() place the devnode->(un)register tests and assignments under the devnode lock as well: this has to be in a critical block.

| * [media] cec: rename cec_devnode fhs_lock to just lockHans Verkuil2016-08-221-3/+3
| | | | | | | | | | | | | | | | This lock will be used to protect more than just the fhs list. So rename it to just 'lock'. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* | [media] cec: Delete an unnecessary check before the function call ↵Markus Elfring2016-08-241-2/+1
|/ | | | | | | | | | | | | "rc_free_device" The rc_free_device() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

* [media] cec: fix Kconfig dependency problemsHans Verkuil2016-07-081-5/+5
| | | | | | | | | | | | | - Use IS_REACHABLE(RC_CORE) instead of IS_ENABLED: if cec is built-in and RC_CORE is a module, then CEC can't reach the RC symbols. - Both cec and cec-edid should be bool and use the same build 'mode' as MEDIA_SUPPORT (just as is done for the media controller code). - Add a note to staging that this should be changed once the cec framework is moved out of staging.

* [media] cec: add HDMI CEC framework (core)Hans Verkuil2016-06-281-0/+409
The added HDMI CEC framework provides a generic kernel interface for HDMI CEC devices. Note that the CEC framework is added to staging/media and that the cec.h and cec-funcs.h headers are not exported yet. While the kABI is mature, I would prefer to allow the uABI some more time before it is mainlined in case it needs more tweaks. This adds the cec-core.c, media/cec.h and cec-priv.h sources.
