No need for BUG_ON, WARN_ON is a lot friendlier. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2023-04-15media: common: saa7146: drop 'fmt' from struct saa7146_bufHans Verkuil
Use the video_fmt in saa7146_vv instead of having a pointer to it in struct saa7146_buf. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2023-04-15media: common: saa7146: disable clippingHans Verkuil
The patch removing overlay support also removed the old saa7146_disable_clipping() function, but that is needed in order to capture video. Without this the Hexium cards won't show any video.

2023-03-20media: saa7146: drop overlay supportHans Verkuil
Destructive overlay support (i.e. where the video frame is DMA-ed straight into a framebuffer) is effectively dead. It was a necessary evil in the early days when computers were not fast enough to copy SDTV video frames around, but today that's no longer a problem. It requires access to the framebuffer memory, which is a bad idea and very hard to do safely. In addition, in drm it is today almost impossible to get hold of the framebuffer address. So drop support for this. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2023-02-09media: Revert "media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci"Hans Verkuil
This reverts commit e33fdb5a02490059e2f48ced2c038c8a46c6476d. The saa7146-based devices are still in use, esp. for DVB. So move these drivers back to mainline. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2022-08-29media: saa7146: deprecate hexium_gemini/orion, mxb and ttpciHans Verkuil
Deprecate the hexium_gemini, hexium_orion, mxb and ttpci saa7146-based drivers: these drivers do not use the vb2 framework for video streaming, instead it uses the old videobuf framework. We want to get rid of these old drivers, so deprecated these for future removal.

2015-11-17[media] include/media: move driver interface headers to a separate dirMauro Carvalho Chehab
Let's not mix headers used by the core with those headers that are needed by some driver-specific interface header. The headers used on drivers were manually moved using: mkdir include/media/drv-intf/ git mv include/media/cx2341x.h include/media/cx25840.h \ include/media/exynos-fimc.h include/media/msp3400.h \ include/media/s3c_camif.h include/media/saa7146.h \ include/media/saa7146_vv.h include/media/sh_mobile_ceu.h \ include/media/sh_mobile_csi2.h include/media/sh_vou.h \ include/media/si476x.h include/media/soc_mediabus.h \ include/media/tea575x.h include/media/drv-intf/ And the references for those headers were corrected using: MAIN_DIR="media/" PREV_DIR="media/" DIRS="drv-intf/" 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>
