[media] v4l: omap4iss: Add support for OMAP4 camera interface - CSI receivers This adds a very simplistic driver to utilize the CSI2A interface inside the ISS subsystem in OMAP4, and dump the data to memory. Check Documentation/video4linux/omap4_camera.txt for details. This commit adds CSI receivers support.

[media] include/media: move platform_data to linux/platform_data/media Let's not mix platform_data headers with the core headers. Instead, let's create a subdir at linux/platform_data and move the headers to that common place, adding it to MAINTAINERS. The headers were moved with: mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/ And the references fixed with this script: MAIN_DIR="linux/platform_data/" PREV_DIR="media/" 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$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>
