2015-08-11[media] mt9v032: fix uninitialized variable warningHans Verkuil1-1/+1

2015-08-11[media] v4l2: move tracepoint generation into separate filePhilipp Zabel3-1/+14
To compile videobuf2-core as a module, the vb2_* tracepoints must be exported from the videodev module. Instead of exporting vb2 tracepoint symbols from v4l2-ioctl.c, move the tracepoint generation into a separate file. This patch fixes the following build error in the modpost stage, introduced by 2091f5181c66 ("[media] videobuf2: add trace events"): ERROR: "__tracepoint_vb2_buf_done" undefined! ERROR: "__tracepoint_vb2_dqbuf" undefined! ERROR: "__tracepoint_vb2_qbuf" undefined! ERROR: "__tracepoint_vb2_buf_queue" undefined!

2015-08-11[media] vivid: support cvt, gtf timings for video outPrashant Laddha1-2/+13
The generation of cvt, gtf timings is already supported by v4l2-ctl. This patch adds support for setting cvt,gtf timings for video out. While enabling cvt,gtf in vivid capture, the vivid video out was missed out. Adding it now.

2015-08-11[media] media: adv7604: reduce support to first (digital) inputWilliam Towle1-3/+14
Using adv7611_read_cable_det() for ADV7612 means that full support for '.max_port = ADV7604_PAD_HDMI_PORT_B,' isn't available due to the need for multiple port reads to determine cable detection, and an agreed mechanism for communicating the separate statuses. This patch replaces adv7611_read_cable_det() with a functionally identical copy, commented appropriately. Earlier submissions [leading to commit 8331d30b] also set .cp_csc, which is used in a cp_read() call within adv76xx_log_status().

Prior to commit f862f57d ("[media] media: i2c: ADV7604: Migrate to regmap"), the local variable 'val' contained the combined register reads used in the chipset version ID test.

2015-08-11[media] usbvision: remove power_on_at_open and timed power offHans Verkuil3-116/+9
This causes lots of problems and is *very* slow as well. One of the main problems is that this prohibits the use of the control framework since subdevs will be unloaded on power off which is not allowed as long as they are used by a usb device. Apparently the reason for doing this is to turn off a noisy tuner. My hardware has no problem with that, and I wonder whether the hardware with that noisy tuner wasn't just functioning improperly as I have never heard of noisy tuners. Contact me if you have one of those devices and I can take a look whether the tuner can't be powered off if necessary by letting the tuner subdevice go into standby mode. Unloading the tuner module is just evil and is not the right approach. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
