      [media] adv7604/adv7842: fix quantization range handling · fd74246d
      由 Hans Verkuil 提交于 
      Fix a number of bugs that appeared when support for mediabus formats was
added:

- Support for V4L2_DV_RGB_RANGE_FULL/LIMITED should only be enabled
  for HDMI RGB formats, not for YCbCr formats. Since, as the name
  says, this setting is for RGB only. So read the InfoFrame to check
  the format.

- the quantization range for the pixelport depends on whether the
  mediabus code is RGB or not: if it is RGB, then produce full range
  RGB values, otherwise produce limited range YCbCr values.

  This means that the op_656_range and alt_data_sat fields of the
  platform data are no longer used and these will be removed in a
  following patch.

- when setting up a new format the RGB quantization range settings
  were never updated. Do so, since this depends on the format.

- fix the log_status output which was confusing and incorrect.

      [media] adv7842: Remove deprecated create_singlethread_workqueue · 1d3e1543
      由 Bhaktipriya Shridhar 提交于 
      The workqueue "work_queues" enables hotplugging.
It has a single work item(&state->delayed_work_enable_hotplug) and hence
doesn't require ordering. Also, it is not being used on a memory
reclaim path. Hence, the singlethreaded workqueue has been replaced with
the use of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

Work item has been sync cancelled in adv7842_remove() to ensure
that there are no pending tasks while disconnecting the driver.

      [media] include/media: split I2C headers from V4L2 core · b5dcee22
      由 Mauro Carvalho Chehab 提交于 
      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] v4l2-dv-timings: add support for reduced blanking v2 · 5fea1bb7
      由 Prashant Laddha 提交于 
      Added support for reduced blanking version 2 (RB v2) in cvt timings.
Standard specifies a fixed vsync pulse of 8 lines to indicate RB v2
timings. Vertical back porch is fixed at 6 lines and vertical front
porch is remainder of vertical blanking time.

For RB v2, horizontal blanking is fixed at 80 pixels. Horizontal sync
is fixed at 32. All horizontal timing counts (active pixels, front,
back porches) can be specified upto a precision of 1.

RB v2 allows for non standard aspect ratios. In RB v2 vsync does not
indicate aspect ratio. In absence of aspect ratio v4l2_detect_cvt()
cannot calculate image width from image height. Hence extending the
v4l2_detect_cvt() to pass image width in case of RB v2.
