media: bttv: drop overlay support 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.

[media] include/media: split I2C headers from V4L2 core Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place. That makes harder to identify what core headers should be documented and what headers belong to I2C drivers that are included only by bridge/main drivers that would require the functions provided by them. Let's move those i2c specific files to its own subdirectory. The files to move were produced via the following script: mkdir include/media/i2c (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done And the references corrected via this script: MAIN_DIR="media/" PREV_DIR="media/" DIRS="i2c/" 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 Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

[media] bttv: Convert to generic TEA575x interface Remove tea575x-specific code from bttv and use the common driver instead. Only set_frequency is implemented (signal/stereo detection or seek would require more changes to bttv). It works fine on Video Highway Xtreme (it actually makes the radio usable as it currently cannot be tuned properly). Miro/Pinnacle is untested but seems to be simple and should work. However, I don't understand the Terratec Active Radio Upgrade code. The HW seems to need IOR, IOW and CSEL signals that were taken from ISA bus on older cards (IOR and IOW directly and CSEL from some address decoder) and are emulated here using GPIOs. But the code manipulating these signals in bttv seems to be broken - it never asserts the IOR signal. If anyone has this HW, please test if I got that right.

[media] bttv: do not switch to the radio tuner unless it is accessed Just opening the radio tuner should not cause a switch to the radio tuner. Only after calling g/s_tuner or g/s_frequency should this happen. This prevents audio being unmuted as soon as the driver is loaded because some process opens /dev/radioX just to see what sort of node it is, which switches on the radio tuner and unmutes audio. This code can be improved further by actually keeping track of who owns the tuner and returning -EBUSY if switching tuner modes will cause problems. But for now just fix the annoying case where on boot the radio turns on automatically. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
