If reduced fps flag is set then check if other necessary conditions are true for the given bt timing. If yes, then reduce the frame rate. For vivid transmitter, timeperframe_vid_out controls the frame rate. Adjusting the timeperframe_vid_out by scaling down pixel clock by factor of 1000 / 1001.

Added a helper function to check necessary conditions required for reduced fps. The reduced fps is supported for CVT and CEA861 timings. CVT supports reduced fps only if reduced blanking v2 (indicated by vsync = 8) is true. Whereas CEA861 supports reduced fps if V4L2_DV_FL_CAN_REDUCE_FPS flag is true.

When a V4L2 sub-device backed by a DT or ACPI based device was removed, the device was unregistered as well which certainly was not intentional, as the client device would not be re-created by simply reinstating the V4L2 sub-device (indeed the device would have to be there first!). Skip unregistering the device in case it has non-NULL of_node or fwnode.

Initialization of the ADV7180 chip fails on the Renesas R8A7790-based Lager board about 50% of the time. This patch resolves the issue by increasing the minimum delay after reset from 2 ms to 5 ms, following the recommendation in the ADV7180 datasheet: "Executing a software reset takes approximately 2 ms. However, it is recommended to wait 5 ms before any further I2C writes are performed."

The sh-vou driver has been converted from videobuf to videobuf2, but the Kconfig file still lists VIDEOBUF_DMA_CONTIG as a dependency. Consequently we can build the driver without VIDEOBUF2_DMA_CONTIG and get a link error: drivers/built-in.o: In function `sh_vou_probe': vf610-ocotp.c:(.text+0x2dbf5c): undefined reference to `vb2_dma_contig_init_ctx' vf610-ocotp.c:(.text+0x2dc0b4): undefined reference to `vb2_dma_contig_cleanup_ctx' vf610-ocotp.c:(.text+0x2dc144): undefined reference to `vb2_dma_contig_memops' drivers/built-in.o: In function `sh_vou_remove': vf610-ocotp.c:(.text+0x2dc190): undefined reference to `vb2_dma_contig_cleanup_ctx' This changes the dependency to VIDEOBUF2_DMA_CONTIG instead.

cpia2_usb_disconnect() seems to be missing a memory barrier which might cause the waker to not notice the waiter and miss sending a wake_up as in the following figure. cpia2_usb_disconnect sync ------------------------------------------------------------------------ mutex_unlock(&cam->v4l2_lock); if (waitqueue_active(&cam->wq_stream)) /* The CPU might reorder the test for the waitqueue up here, before prior writes complete */ /* wait_event_interruptible */ /* __wait_event_interruptible */ /* ___wait_event */ long __int = prepare_to_wait_event( &wq, &__wait, state); if (!cam->streaming || frame->status == FRAME_READY) cam->curbuff->status = FRAME_READY; cam->curbuff->length = 0; schedule() ------------------------------------------------------------------------ The attached patch removes the call to waitqueue_active() leaving just wake_up() behind. This fixes the problem because the call to spin_lock_irqsave() in wake_up() will be an ACQUIRE operation. I found this issue when I was looking through the linux source code for places calling waitqueue_active() before wake_up*(), but without preceding memory barriers, after sending a patch to fix a similar issue in drivers/tty/n_tty.c (Details about the original issue can be found here: https://lkml.org/lkml/2015/9/28/849).

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.

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.

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.

Improve the comments at the header, removing kernel-doc tag from where it doesn't belong, grouping the legacy tuner functions, and improving the text. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

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 <mchehab@osg.samsung.com>

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.
