2017-07-19media: omap3isp: Destroy CSI-2 phy mutexes in error and module removalSakari Ailus
The CSI-2 phy driver did initialise mutexes in its init function but there was no corresponding cleanup function destroying them. Fix that. Also clean up ISP module initialisation a little.

2017-07-18media: cec-pin: add low-level pin hardware supportHans Verkuil
Add support for CEC hardware that relies on low-level pin polling or GPIO interrupts. One example is the Allwinner SoC. But any GPIO-based CEC implementation can use this as well. A GPIO implementation is very suitable as well for debugging: it can use interrupts to detect state changes and report it. Userspace can then verify if the bus traffic is correct. This also makes error injection possible. The disadvantage is that it is hard to get the timings right since linux isn't a hard realtime system. In general on an idle system it works quite well, but under load the timer will miss its mark every so often. The debugfs file /sys/kernel/debug/cec/cecX/status gives some statistics with respect to the timer overruns. When the adapter is unconfigured and the low-level driver supports interrupts, then the interrupt will be used to detect changes. This should be quite accurate. But when the adapter is configured a hrtimer has to be used. The hrtimer implements a state machine where for each state the code will read the bus or drive the bus and go on to the next state. It will re-arm the timer with a delay based on the next state.

2017-07-18media: cec: rework the cec event handlingHans Verkuil
Event handling was always fairly simplistic since there were only two events. With the addition of pin events this needed to be redesigned. The state_change and lost_msgs events are now core events with the guarantee that the last state is always available. The new pin events are a queue of events (up to 64 for each event) and the oldest event will be dropped if the application cannot keep up. Lost events are marked with a new event flag.

Currently the transmit_(attempt_)done and received_msg functions set the timestamp themselves. For the upcoming low-level pin API we need to pass this as an argument instead. So make _ts variants that allow the caller to specify the timestamp.

2017-07-18media: cec: only increase the seqnr if CEC_TRANSMIT would return 0Hans Verkuil
The transmit code would increase the sequence number first thing, even though CEC_TRANSMIT would return an error due to a malformatted cec_msg struct later on. While valid behavior, this had the disadvantage of producing holes in the sequence list that made debugging harder. Only increase the sequence number when the whole message is validated. When debugging (i.e. with cec-ctl -M) the sequence numbering is now nicely increasing by 1 per message.

2017-07-17media: vimc: set id_table for platform driversJavier Martinez Canillas
The vimc platform drivers define a platform device ID table but these are not set to the .id_table field in the platform driver structure. So the platform device ID table is only used to fill the aliases in the module but are not used for matching (works because the platform subsystem fallbacks to the driver's name if no .id_table is set). But this also means that the platform device ID table isn't used if the driver is built-in, which leads to the following build warning: This causes the following build warnings when the driver is built-in: drivers/media/platform/vimc//vimc-capture.c:528:40: warning: ‘vimc_cap_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_cap_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ drivers/media/platform/vimc//vimc-debayer.c:588:40: warning: ‘vimc_deb_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_deb_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ drivers/media/platform/vimc//vimc-scaler.c:442:40: warning: ‘vimc_sca_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_sca_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ drivers/media/platform/vimc//vimc-sensor.c:376:40: warning: ‘vimc_sen_driver_ids’ defined but not used [-Wunused-const-variable=] static const struct platform_device_id vimc_sen_driver_ids[] = { ^~~~~~~~~~~~~~~~~~~ Reported-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Suggested-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Helen Koike <helen.koike@collabora.com> Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com>
