2011-10-15[media] cx23885: Stop the risc video fifo before reconfiguring itSteven Toth1-0/+3
Safety reasons. We shouldn't be trying to reconfigure a risc processor instruction queue unless it's stopped. Signed-off-by: Steven Toth <stoth@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-10-15[media] cx23885: Avoid incorrect error handling and reportingSteven Toth1-10/+10
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).

2011-10-15[media] cx23885: Avoid stopping the risc engine during buffer timeoutSteven Toth1-4/+0
1. Removed the verbose 'dump channel state to console', very noisy in weak signal conditions. 2. No need for the video buffer timeout to stop the risc engine here. Clearer and easier to maintain if start_video_dma() is the single place that this is done. Signed-off-by: Steven Toth <stoth@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-10-15[media] cx25840: Enable support for non-tuner LR1/LR2 audio inputsSteven Toth2-1/+20
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 Canillas1-1/+16
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 Gortmaker3-2/+4
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.

2011-10-08[media] saa7115: Trust that V4L2 core will fill the maskMauro Carvalho Chehab1-7/+12
Instead of using V4L2_STD_ALL when no standard is detected, trust that the maximum allowed standards are already filled by the V4L2 core. It is better this way, as the bridge and/or the audio decoder may have some extra restrictions to some video standards. This also allow other devices like audio and tuners to contribute to standards detection, when they support such feature. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-10-08[media] v4l2-ioctl: Fill the default value for VIDIOC_QUERYSTDMauro Carvalho Chehab1-0/+8
According with the V4L2 API spec: "When detection is not possible or fails, the set must contain all standards supported by the current video input or output." The V4L2 core has the mask with all supported standards already. So, apply it. Driver and subdevs can then just remove standards from the mask, as they're able of detecting audio, video and frames frequency. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
