2011-10-24mfd: remove CONFIG_MFD_SUPPORTArnd Bergmann
We currently have two symbols to control compilation the MFD subsystem, MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required at all, it only hides the submenu when not set, with the effect that Kconfig warns about missing dependencies when another driver selects an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu back from menuconfig into a plain menu simplifies the Kconfig syntax for those kinds of users and avoids the surprise when the menu suddenly appears because another driver was enabled that selects this symbol.

2011-10-19[media] videodev: fix a NULL pointer dereference in v4l2_device_release()Antonio Ospite
The change in 8280b66 does not cover the case when v4l2_dev is already NULL, fix that. With a Kinect sensor, seen as an USB camera using GSPCA in this context, a NULL pointer dereference BUG can be triggered by just unplugging the device after the camera driver has been loaded.

2011-10-19[media] adv7175: Make use of media bus pixel codesChristian Gmeiner
The ADV7175A/ADV7176A can operate in either 8-bit or 16-bit YCrCb mode. * 8-Bit YCrCb Mode This default mode accepts multiplexed YCrCb inputs through the P7-P0 pixel inputs. The inputs follow the sequence Cb0, Y0 Cr0, Y1 Cb1, Y2, etc. The Y, Cb and Cr data are input on a rising clock edge. * 16-Bit YCrCb Mode This mode accepts Y inputs through the P7–P0 pixel inputs and multiplexed CrCb inputs through the P15–P8 pixel inputs. The data is loaded on every second rising edge of CLOCK. The inputs follow the sequence Cb0, Y0 Cr0, Y1 Cb1, Y2, etc. Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-10-19[media] em28xx: implement VIDIOC_ENUM_FRAMESIZESMauro Carvalho Chehab
Pidgin uses gstreamer (and libv4l) to work. Without implementing this ioctl, it won't detect properly the size range, and driver will fail. So, this patch is required, in order to use an em27xx webcam, like Silvercrest. The pigdin/gstreamer/libv4l needs to be fixed, as it shouldn't assume that all drivers will implement this optional ioctl, but, at least now, devices with em28xx have a better chance of working with pidgin.

2011-10-14[media] cx23885: Stop the risc video fifo before reconfiguring itSteven Toth

2011-10-14[media] cx23885: Avoid incorrect error handling and reportingSteven Toth
Previous driver over-reported errors and stopped the video fifo (causing video to stop) if 1) A risc error occured 2) The risc processor detected that it has missing lines in the video frame 3) The risc fifo is about to overflow. The previous driver reported all three of these cases as risc errors when this is technically not correct. So, the function was cleaned up. 1. Ensure that risc opcode related errors are correctly shown as such, and not overly reported for non-risc-opcode cases. 2. Ensure that line sync and overflow errors are not reported as opcode errors. 3. Ensure that only the risc-op-code case can stop the fifo and dump channel / risc processor information. The net result is that if video becomes unstable, cable disconnect, this will not trigger a stop of the video firmware (due to missing lines errors).

2011-10-14[media] cx23885: Avoid stopping the risc engine during buffer timeoutSteven Toth

2011-10-14[media] cx25840: Enable support for non-tuner LR1/LR2 audio inputsSteven Toth
The change effects cx23885 boards only and preserves support for existing boards. Essentially, if we're using baseband audio into the cx23885 AV core then we have to patch registers. The cx23885 driver will call with either CX25840_AUDIO8 to signify tuner audio or AUDIO7 to signify baseband audio. If/When we become more comfortable with this change across a series of products then we may decide to relax the cx23885 only restriction.

2011-10-08[media] tvp5150: Add video format registers configuration valuesJavier Martinez Canillas
The tvp5150 video decoder has two operation modes to configure the video standard used. If auto-switch mode is enable, the device can sense the signal and detect which video standard the device is operating. Also the device can be forced to use a user defined video standard. Each operation mode uses a different register and the bitmask values to represent each standard is different. So we add video standard constants for both autoswitch and no-autoswitch mode.

2011-10-08[media] drivers/media: fix dependencies in video mt9t001/mt9p031Paul Gortmaker
Both mt9t001.c and mt9p031.c have two identical issues, those being that they will need module.h inclusion for the upcoming cleanup going on there, and that their dependencies don't limit selection of configs that will fail to compile as follows: The related config options are CONFIG_MEDIA_CONTROLLER and CONFIG_VIDEO_V4L2_SUBDEV_API. Looking at the code, it appears that the driver was never intended to work without these enabled, so add a dependency on CONFIG_VIDEO_V4L2_SUBDEV_API, which in turn already has a dependency on CONFIG_MEDIA_CONTROLLER.
