[media] V4L: soc-camera: remove soc-camera bus and devices on it

2011-07-27T20:56:08Z

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. Signed-off-by: Guennadi Liakhovetski Acked-by: Paul Mundt Signed-off-by: Mauro Carvalho Chehab

[media] V4L: mx3_camera: remove redundant calculations

2011-07-27T20:53:21Z

soc_camera core now performs the standard .bytesperline and .sizeimage calculations internally, no need to duplicate in drivers. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] Stop using linux/version.h on the remaining video drivers

2011-07-27T20:53:16Z

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. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] V4L: soc-camera: a missing mediabus code -> fourcc translation is not critical

2011-05-20T15:06:46Z

soc_mbus_get_fmtdesc() returning NULL means only, that no standard mediabus code -> fourcc conversion is known, this shouldn't be treated as an error by drivers. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] V4L: soc-camera: add a new packing for YUV 4:2:0 type formats

2011-05-20T15:05:08Z

12-bit formats, similar to YUV 4:2:0 occupy 3 bytes for each two pixels and cannot be described by any of the existing SOC_MBUS_PACKING_* macros. This patch adds a new one SOC_MBUS_PACKING_1_5X8 to describe such formats and extends soc_mbus_samples_per_pixel() to support it.

[media] V4L: mx3_camera: implement .stop_streaming()

2011-05-20T14:52:53Z

The .stop_streaming() videobuf2 operation has to be implemented to guarantee, that video buffers are not written to after a STREAMOFF. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] V4L: mx3_camera: convert to videobuf2

2011-03-21T23:32:15Z

Now that soc-camera supports videobuf API v1 and v2, camera-host drivers can be converted to videobuf2 individually. This patch converts the mx3_camera driver. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] V4L: mx3_camera: fix capture issues for non 8-bit per pixel formats

2011-03-21T23:32:14Z

If the camera was set to output formats like RGB565 YUYV or SBGGR10, the resulting image was scrambled due to erroneous interpretations of horizontal parameter's units. This patch in fourcc_to_ipu_pix, eliminate also the pixel formats mappings that, first are not used within mainline code and second, standing at the datasheets, they will not work properly: The IPU internal bus support only the following data formatting (44.1.1.3 Data Flows and Formats): 1 YUV 4:4:4 or RGB-8 bits per color component 2 YUV 4:4:4 or RGB-10 bits per color component 3 Generic data (from sensor to the system memory only) And format conversions are done: - from memory: unpacking from other formats to IPU supported ones - to memory: packing in the inverse order. So, assigning a packing/unpacking strategy to the IPU for those formats will produce a packing to memory and not the inverse.

[media] V4L: mx3_camera: correct 'sizeimage' value reporting

2011-03-21T23:32:14Z

The 'pix->width' field may be updated in mx3_camera_set_fmt() to fulfill the IPU stride line alignment requirements. If this update takes place, the 'fmt.pix.sizeimage' field in the struct v4l2_format stucture returned by VIDIOC_S_FMT is wrong. We need to update the 'pix->sizeimage' field in the mx3_camera_set_fmt() function to fix this issue.

[media] v4l: soc-camera: switch to .unlocked_ioctl
