* [media] Support for Terratec G1Teka2011-11-03
| | | | | | | | | | | | Hi, This is a little patch to support Terratec G1 (based on Terratec Grabby). It works perfectly on my pc (Ubuntu 11.04 / Kernel 2.6.38). Best regards, Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] cx25821: off by one in cx25821_vidioc_s_input()Dan Carpenter2011-11-03
| | | | | | | | | | | | If "i" is 2 then when we call cx25821_video_mux() we'd end up going past the end of the cx25821_boards[dev->board]->input[]. The INPUT() macro obfuscates what's going on in that function so it's a bit hard to follow. And as Mauro points out the hard coded 2 is not very helpful.

In preparation for preview engine cropping support, move them all to isppreview.c and rename them to PREV_{MIN|MAX}_{IN|OUT}_{WIDTH|HEIGHT}*.

Following controls are available: manual/auto exposure and gain, power line frequency (anti-flicker), saturation, sharpness, brightness, contrast, white balance temperature, color effects, horizontal/vertical image flip, frame interval, auto white balance.

However some devices are capable of automatically detecting the frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them.

* [media] V4L: soc-camera: make (almost) all client drivers re-usable outside ↵Guennadi Liakhovetski2011-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | of the framework The most important change in this patch is direct linking to struct soc_camera_link via the client->dev.platform_data pointer. This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
