Replace the obsolete field ctrl_class with "which". Make sure it not used in future modules by commenting out the field with ifndef __KERNEL_ . The field cannot be simply removed because that would be change on the kenel API to the userspace (and we don't like that). Signed-off-by:

So it can be used to get the default value of a control. Without this change it is not possible to get the default value of array controls. Signed-off-by:

"len" comes from dvb_video_ioctl() and there is a possibility that it is zero. We do a divide by len later in the function so that's not ok. Signed-off-by:

The issue here is that we there is a static checker warning because we have a user controlled volume setting and we cap the upper bound but we allow negative numbers. Negative volumes don't make sense, so let's make these variables unsigned. Signed-off-by:

In the 3.17 kernel the poll() behavior changed for output streams: as long as not all buffers were queued up poll() would return that userspace can write. This is fine for the write() call, but when using stream I/O this changed the behavior since the expectation was that it would wait for buffers to become available for dequeuing. This patch only enables the check whether you can queue buffers for file I/O only, and skips it for stream I/O. Signed-off-by:

If vivid is loaded with the no_error_inj=1 option, then v4l2-compliance will fail for the video and vbi output nodes because the vivid control class has no controls. Don't add the control class for video and vbi output if no_error_inj is true. Signed-off-by:

The term "input stream" is confusing since it is not clear whether this is an input stream from the point of view of the application or from the point of view of the hardware. So replace it with the more standard term "capture stream". Signed-off-by:

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:Lee Jones <lee.jones@linaro.org> Acked-by:

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: -

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.

The file include/media/lirc.h describes a public interface and should thus be a public header. See kernel bug https://bugzilla.kernel.org/show_bug.cgi?id=75751 which has a manpage describing the interface + an acknowledgment that this info belongs to uapi. Signed-off-by:

Commit 5240f4e6 ("[media] DocBook/media/Makefile: Avoid make htmldocs to fail") introduced a mkdir which is always called through install_media_images from the Documentation/DocBook/Makefile htmldocs rule. If you run 'make htmldocs' more than once you get: mkdir: cannot create directory ‘./Documentation/DocBook//media_api’: File exists Add -p to the mkdir to continue no matter if the dir already exists.

Mauro Carvalho Chehab authored
The get_state()/set_state and the corresponding data types (struct tuner_state and enum tuner_param) are old DVB interfaces that came from the DVBv3 time. Nowadays, set_params() provide a better way to set the tuner and demod parameters. So, no need to keep those legacy stuff, as all drivers that were using it got converted. With this patch, all kABI elements at dvb_frontend.h are now documented. Signed-off-by: -
Mauro Carvalho Chehab authored
It is tricky to get rid of those ops here, as the stv0299 driver wants to set frequency in separate from setting the bandwidth. So, we use a small trick: we temporarely fill the cache with 0 for either frequency or bandwidth and add some logic at set_params to only change the property(ies) that aren't zero. Signed-off-by: -
Mauro Carvalho Chehab authored
Those ops aren't used by any driver, with is weird. I suspect that mantis_vb3030 driver were not working properly... Anyway, now that the driver uses the set_parms, the DVB frontend core should do the right thing. Signed-off-by: -
Mauro Carvalho Chehab authored
Those callbacks are meant to be used only on some very specific cases. There's absolutely no need to do that at tda8261, as the only parameter that it allows to be set/get is the frequency. So, use the standard get_params() and get_frequency() kABI ops. There's no need to touch at any bridge driver, as all interactions are done via the macros at tda8261_cfg.h. Signed-off-by: -

Those two callbacks are the ones that should be used by normal DVB frontend drivers. Add support for them. Signed-off-by: -

On tda665x, set_state only sets frequency. As the kABI for set_state is meant to be used only on special cases, split the function into two, in order to allow it to be latter used by a DVBv5 cache params logic. Signed-off-by: -
Mauro Carvalho Chehab authored
The stb6100 driver has a struct tuner_state on its state struct, that it is used only to store the bandwidth. Even so, this struct is not really used, as every time the bandwidth is get or set, it goes through the hardware. So, get rid of that. Signed-off-by: -
Mauro Carvalho Chehab authored
There are several tuner_param values that aren't by any driver or core: DVBFE_TUNER_TUNERSTEP DVBFE_TUNER_IFFREQ DVBFE_TUNER_REFCLOCK DVBFE_TUNER_IQSENSE DVBFE_TUNER_DUMMY Several of those correspond to the values at the tuner_state struct with is also only initialized by not used anyware: u32 tunerstep; u32 ifreq; u32 refclock; It doesn't make sense to keep anything at the kABI that it is not used. So, get rid of them. Signed-off-by: -

The DocBook description of this header has two issues: - It calls the Kernel ABI as API, instead of kABI; - It mentions that the DVB frontend kABI is not described within the document. As this will actually generate a single DocBook, this is actually not true, now that the documentation for the frontend was added. So, fix both issues. Signed-off-by: -

This function is used mainly at the DVB core, in order to provide emulation for a legacy ioctl. The only current exception is the stv0299 driver, with takes more than 8ms to switch voltage, breaking the emulation for FE_DISHNETWORK_SEND_LEGACY_CMD. Document that. Signed-off-by:
