[media] V4L: mx3-camera: prepare to support multi-size buffers

2011-11-03T20:28:39+00:00

Prepare the mx3_camera friver to support the new VIDIOC_CREATE_BUFS and
VIDIOC_PREPARE_BUF ioctl()s. The .queue_setup() vb2 operation must be
able to handle buffer sizes, provided by the caller, and the
.buf_prepare() operation must not use the currently configured frame
format for its operation, which makes it superfluous for this driver.
Its functionality is moved into .buf_queue().

[media] V4L: vb2: prepare to support multi-size buffers

2011-11-03T20:28:28+00:00

In preparation for the forthcoming VIDIOC_CREATE_BUFS ioctl add a
"const struct v4l2_format *" argument to the .queue_setup() vb2
operation.

[media] V4L: mx3_camera: convert to the new mbus-config subdev operations

2011-11-03T20:27:46+00:00

Switch from soc-camera specific .{query,set}_bus_param() to V4L2
subdevice .[gs]_mbus_config() operations.

[media] media: vb2: dma contig allocator: use dma_addr instread of paddr

2011-09-06T18:05:10+00:00

Use the correct 'dma_addr' name for the buffer address. 'paddr' suggested
that this is the physical address in system memory. For most ARM platforms
these two are the same, but this is not a generic rule. 'dma_addr' will
also point better to dma-mapping api.

[media] media: vb2: change plane sizes array to unsigned int[]

2011-09-06T18:04:27+00:00

Plane sizes array was declared as unsigned long[], while unsigned int is
more than enough for storing size of the video buffer. This patch reduces
the size of the array by definiting it as unsigned int[].

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

2011-07-27T20:56:08+00:00

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: mx3_camera: remove redundant calculations

2011-07-27T20:53:21+00:00

soc_camera core now performs the standard .bytesperline and .sizeimage
calculations internally, no need to duplicate in drivers.

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

2011-07-27T20:53:16+00:00

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.

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

2011-05-20T15:06:46+00:00

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.

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

2011-05-20T15:05:08+00:00

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.
