* [media] V4L: mx2_camera: convert to the new mbus-config subdev operationsGuennadi Liakhovetski2011-11-03
| | | | | | | | Switch from soc-camera specific .{query,set}_bus_param() to V4L2 subdevice .[gs]_mbus_config() operations. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] V4L: soc-camera: remove soc-camera bus and devices on itGuennadi Liakhovetski2011-07-27
| | | | | | | | | | | Now that v4l2 subdevices have got their own device objects, having one more device in soc-camera clients became redundant and confusing. This patch removes those devices and the soc-camera bus, they used to reside on.

* [media] V4L: mx2_camera: .try_fmt shouldn't failGuennadi Liakhovetski2011-07-27
| | | | | | | | If the user is requesting too large a frame, instead of failing select an acceptable geometry, preserving the requested aspect ratio. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] Stop using linux/version.h on the remaining video driversMauro Carvalho Chehab2011-07-27
| | | | | | | | | | | | | Standardize the remaining video drivers to return the API version for the VIDIOC_QUERYCAP version, instead of a per-driver version. Those drivers had the version updated more recently or are SoC drivers. Even so, it doesn't sound a good idea to keep a per-driver version control, so, let's use the per-subsystem version control instead.

* V4L/DVB: videobuf: add queue argument to videobuf_waiton()Hans Verkuil2010-10-20
| | | | | | | | | | | | | | | | videobuf_waiton() must unlock and relock ext_lock if it has to wait. For that to happen it needs the videobuf_queue pointer. Don't attempt to unlock/relock q->ext_lock unless it was locked in the first place. vb->state has to be protected by a spinlock to be safe. This patch is based on code from Mauro Carvalho Chehab <mchehab@redhat.com>.

* V4L/DVB: mx2_camera: fix for list bufnum in frame_done_emmaMichael Grzeschik2010-08-08
| | | | | | | | | | The emma uses bufnum 1 and 0. This patch tells the bufqueue to change the next buffer to the next one and not the current one. Otherwise the BUG_ON above will trigger everytime.

* mx2_camera: Add soc_camera support for i.MX25/i.MX27Baruch Siach2010-07-28
This is the soc_camera support developed by Sascha Hauer for the i.MX27. Alan Carvalho de Assis modified the original driver to get it working on more recent kernels. I modified it further to add support for i.MX25. This driver has been tested on i.MX25 and i.MX27 based platforms.
