2016-11-16[media] cec.h/cec-funcs.h: don't use bool in public headersHans Verkuil
Replace bool by int or __u8 (when used in a struct). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-11-16[media] cec: sanitize msg.flagsHans Verkuil

2016-11-16[media] cec: move the CEC framework out of staging and to mediaHans Verkuil

2016-11-16[media] cec: add proper support for CDC-Only CEC devicesHans Verkuil
CDC-Only CEC devices are CEC devices that can only handle CDC messages, all other messages are ignored. Add a flag to signal that this is a CDC-Only device and act accordingly. Also add helper functions to identify if a CEC device is configured as a CDC-Only device, a second TV, a switch or a processor, since these variations cannot be determined by the logical address alone.

2016-11-16[media] cec: accept two replies for CEC_MSG_INITIATE_ARCHans Verkuil
The CEC_MSG_INITIATE_ARC message is special since it is the ONLY CEC message that accepts two possible valid replies: CEC_MSG_REPORT_ARC_INITIATED and CEC_MSG_REPORT_ARC_TERMINATED. So if the transmitted message is CEC_MSG_INITIATE_ARC and the remote side replied with CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED, then a msg->reply value of CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED will match either reply. I thought about either adding a second reply2 field, but that's ugly for all other messages that have only one reply, and what if in the future a new message is added that can have three replies? Another option would be to add a cec_msg flag, but really, the combination of CEC_MSG_REPORT_ARC_INITIATED and a reply value of one of the two possible replies already functions as a flag. Another advantage of this approach is that it is safe to re-use a cec_msg struct. No need to zero a flags field or a reply2 field. So since this really is an exception in the CEC specification, I decided to implement it as an exception as well.

2016-11-16[media] cec: filter invalid messagesHans Verkuil

2016-11-16[media] cec: add CEC_MSG_FL_REPLY_TO_FOLLOWERSHans Verkuil
Give the caller more control over how replies to a transmit are handled. By default the reply will only go to the filehandle that called CEC_TRANSMIT. If this new flag is set, then the reply will also go to all followers. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-11-16[media] cec: add flag to cec_log_addrs to enable RC passthroughHans Verkuil
By default the CEC_MSG_USER_CONTROL_PRESSED/RELEASED messages are passed on to the follower(s) only. If the new CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag is set in the flags field of struct cec_log_addrs then these messages are also passed on to the remote control input subsystem and they will appear as keystrokes. This used to be the default behavior, but now you have to explicitly enable it. This is done to force the caller to think about possible security issues (e.g. if these messages are used to enter passwords).

Add picture aspect ratio information, the CEA-861 VIC (Video Identification Code) and the HDMI VIC to struct v4l2_bt_timings. The picture aspect was chosen rather than the pixel aspect since 1) the CEA-861 standard uses picture aspect, and 2) pixel aspect ratio can become tricky when dealing with pixel repeat timings. While we don't support those yet at the moment, this might become necessary. And in that case using picture aspect ratio makes more sense. And converting picture aspect ratio to pixel aspect ratio is easy enough. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-11-16[media] media: solo6x10: fix lockup by avoiding delayed register writeAndrey Utkin
This fixes a lockup at device probing which happens on some solo6010 hardware samples. This is a regression introduced by commit e1ceb25a1569 ("[media] SOLO6x10: remove unneeded register locking and barriers") The observed lockup happens in solo_set_motion_threshold() called from solo_motion_config(). This extra "flushing" is not fundamentally needed for every write, but apparently the code in driver assumes such behaviour at last in some places. Actual fix was proposed by Hans Verkuil.

2016-11-16[media] DaVinci-VPIF-Display: Use kcalloc() in vpif_probe()Markus Elfring
* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
