- open/close/read and poll need to take the core lock as well. - when the tuner goes to sleep we should set std_set_in_tuner_core to 0 since the tuner loses the firmware at that time. - initialize the tuner if std_set_in_tuner_core == 0 whenever: 1) g/s_tuner, s_std or s_frequency is called 2) read or poll is called 3) streamon is called Signed-off-by:

- V4L2_CAP_AUDIO was set, but enumaudio was not implemented. - audioset was never filled by enum_input - ctrl_ainput was never updated when switching the video input - g_audio was broken due to faulty logic: g_audio should set the index, it doesn't receive it from the user. Signed-off-by:

- define an initial frequency - return an error if g_frequency is called for an invalid tuner index - get the clamped frequency value after setting it: i.e. the tuner driver may clamp the given frequency to a valid frequency range and ctrl_freq should get that actual clamped frequency. - remove obsolete tuner type checks (done by the core).

Add support for vidioc_g_chip_name, allowing AC97 to be implemented as a second chip on the bridge with the name "ac97". v4l2-dbg can just match the name with that string in order to detect a ac97-compliant set of registers. Signed-off-by:

It was just a placeholder and we want to get rid of the AC97 matching define. Also replace MATCH_HOST with MATCH_BRIDGE since we are here anyway. Signed-off-by:

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl. This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver. Signed-off-by:

During the transition to sub-devices several years ago non-subdev drivers had a ' at the end of their driver name to tell them apart from already converted drivers. This check was a left-over from that time and can be removed. Signed-off-by:

In vb2_buffer_done, it would be better the print the value of 'state' (current state of buffer) than to print 'vb->state' which is always VB2_BUF_STATE_ACTIVE. Signed-off-by:

An earlier patch temporarily disabled regional motion detection. This patch adds it back: the 'Motion Detection Enable' control is now a 'Motion Detection Mode'. And to set/get the regional thresholds two new ioctls were added to get/set those thresholds. The BUF_FLAG constants were also updated to prevent clashing with existing buffer flags. Signed-off-by:

As a consequence the ioctl op has been replaced by unlocked_ioctl. Since we are now using the core lock the locking scheme has been simplified as well. The main reason for converting this driver to vb2 was that the locking scheme in v4l2.c was hopeless. It was easier to just convert the driver then to try and salvage a threading and videobuf nightmare. The videobuf2 framework is far, far superior compared to the old videobuf. Signed-off-by:

All fields in solo_enc_fh do not belong there since they refer to global properties. After moving all these fields to solo_enc_dev the solo_dev_fh struct can be removed completely. Note that this also kills the 'listener' feature of this driver. This feature (where multiple filehandles can read the video) is illegal in the V4L2 API. Do this in userspace: it's much more efficient to copy memory than it is to DMA to every listener. Signed-off-by:

- try_fmt should never return -EBUSY. - invalid pix->field values were not mapped to a valid value. - the priv field of struct v4l2_pix_format wasn't zeroed. - the try_fmt error code was not checked in set_fmt. - enum_framesizes/intervals is valid for both MJPEG and MPEG pixel formats. - enum_frameintervals didn't check width and height and reported the wrong range. - s_parm didn't set readbuffers. - don't fail on invalid colorspace, just replace with the valid colorspace. - bytesperline should be 0 for compressed formats.
