[media] media: videobuf2: Move timestamp to vb2_buffer

2015-12-18T15:53:31+00:00

Move timestamp from struct vb2_v4l2_buffer to struct vb2_buffer
for common use, and change its type to u64 in order to handling
y2038 problem. This patch also includes all device drivers' changes related to
this restructuring.

[media] vb2: drop v4l2_format argument from queue_setup

2015-12-18T15:48:19+00:00

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.

After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.

To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

[media] rcar_vin: Remove obsolete platform data support

2015-11-19T10:11:22+00:00

Since commit 3d7608e4c169af03 ("ARM: shmobile: bockw: remove legacy
board file and config"), Renesas R-Car SoCs are only supported in
generic DT-only ARM multi-platform builds.  The driver doesn't need to
use platform data anymore, hence remove platform data configuration.

[media] move media platform data to linux/platform_data/media

2015-11-19T10:09:38+00:00

Now that media has its own subdirectory inside platform_data,
let's move the headers that are already there to such subdir.

After moving those files, the references were adjusted using this
script:

    MAIN_DIR="linux/platform_data/"
    PREV_DIR="linux/platform_data/"
    DIRS="media/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;

[media] atmel-isi: setup YCC_SWAP correctly when using preview path

2015-11-17T17:31:47+00:00

The preview path only can convert UYVY format to RGB data.

To make preview path work correctly, we need to set up YCC_SWAP
according to sensor output and convert them to UYVY.

[media] atmel-isi: add code to setup correct resolution for preview path

2015-11-17T17:29:39+00:00

Not like codec path, preview path can do downsampling, so we should setup
a extra preview width, height for it.

This patch add preview resolution setup without down sampling. So currently
preview path will output same size as sensor output size.

[media] atmel-isi: prepare for the support of preview path

2015-11-17T17:29:19+00:00

Atmel ISI support a preview path which can output RGB data.

So this patch introduces a bool variable to choose which path is
enabled currently. And also we need setup corresponding path registers.

By default the preview path is disabled. We only use Codec path.
