      media: adv*/tc358743/ths8200: fill in min width/height/pixelclock · b945ddac
      由 Hans Verkuil 提交于 
      [ Upstream commit 2912289a518077ddb8214e05336700148e97e235 ]

The v4l2_dv_timings_cap struct is used to do sanity checks when setting and
enumerating DV timings, ensuring that only valid timings as per the HW
capabilities are allowed.

However, many drivers just filled in 0 for the minimum width, height or
pixelclock frequency. This can cause timings with e.g. 0 as width and height
to be accepted, which will in turn lead to a potential division by zero.

Fill in proper values are minimum boundaries. 640x350 was chosen since it is
the smallest resolution in v4l2-dv-timings.h. Same for 13 MHz as the lowest
pixelclock frequency (it's slightly below the minimum of 13.5 MHz in the
v4l2-dv-timings.h header).

      [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] 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.
