[media] v4l2-dev: rename two functions

2012-05-14T18:06:50+00:00

Rename the function v4l2_dont_use_lock to v4l2_disable_ioctl_locking, and rename v4l2_dont_use_cmd to v4l2_disable_ioctl. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] pwc: Fix locking

2012-05-14T12:21:59+00:00

My last locking rework for pwc mistakenly assumed that videbuf2 does its own locking, but it does not! This patch fixes the missing locking by moving over the the video_device lock, and introducing a separate lock for the videobuf2_queue.

pwc: Add support for control events

2012-04-09T11:28:33+00:00

Since the pwc driver already uses v4l2-device, v4l2-fh, and the control framework, all that is needed is hooking up event subscription. Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab

[media] pwc: poll(): Check that the device has not beem claimed for streaming already

2012-03-27T14:42:04+00:00

Some apps which use read() start the streaming through a call to poll(), this means that if another app has already claimed the device for streaming (through for example a s_fmt, or a reqbufs), that the poll should fail instead of getting passed through to vb2_poll. We only check for this when the app is polling for reads, so that ctrl events still work. Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: standardize log start/end message

2012-02-14T18:38:13+00:00

For drivers that properly use the v4l2 framework (i.e. set v4l2_dev in the video_device struct), the start and end messages of VIDIOC_LOG_STATUS are now generated automatically. People tended to forget these, but the v4l2-ctl tool scans for these messages, and it also makes it easier to read the status output in the kernel log. The cx18, ivtv and bttv drivers were changed since they no longer need to log these start/end messages. In saa7164 two empty log_status functions were removed. Also added a helper function to v4l2-ctrl.c that can be used as the vidioc_log_status callback if all you need to do is to log the current control values. This is now used by pwc and vivi.

[media] pwc: Simplify leds parameter parsing

2012-01-16T13:28:13+00:00

This reduces our module init to a simple usb_register() call, so that we can make use of the new upcoming macro's for this. Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab

[media] pwc: Remove dev_hint module parameter

2012-01-16T13:28:12+00:00

The code for this is rather crufty, and being able to tie a device to a specific minor is not really something we want to support in a modern udev based world. Signed-off-by: Hans de Goede Signed-off-by: Mauro Carvalho Chehab
