The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.
This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.
Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

Changing the device name, causes it to be unable to remove the

In randconfig builds that select VIDEO_EM28XX_V4L2 and
MEDIA_SUBDRV_AUTOSELECT, but not MEDIA_CAMERA_SUPPORT, we get
a Kconfig warning:
warning: (VIDEO_EM28XX_V4L2) selects VIDEO_MT9V011 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT)
This avoids the warning by making that 'select' conditional on
MEDIA_CAMERA_SUPPORT. Alternatively we could mark EM28XX as
'depends on MEDIA_CAMERA_SUPPORT', but it does not seem to
have any real dependency on that itself.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.
</script>
use Text::Tabs;
while (<>) {
if ($next ne "") {
$c=$_;
if ($c =~ /^\s+\"(.*)/) {

There are still several places with printk's called directly.

Note that the memops functions now get a struct device pointer instead of

The demodulator needs firmware, available for example here:

The demodulators sit on the same I2C bus and their addresses

their addresses are 0x60 and 0x63.

EMP202 chip inside Terratec Grabby (hw rev 2) seems to require some time
before accessing reliably its registers. Otherwise it returns some values
previously put on the I2C bus.
To account for that period, we delay card setup until we have a proof that
accessing AC97 registers is reliable. We get this proof by polling
AC97_RESET until the expected value is read. We also check that unrelated
registers don't return the same value. This second check handles the case
where the expected value is constantly returned no matter which register
is accessed.

There are some devices, like Terratec Cinergy HTC, where
while the device supports analog TV, the driver is not
capable yet of handling it, because the analog TV driver
was not written.
So, don't bind the em28xx-v4l drivers on such devices.

On em28xx driver, s_stream subdev ops was not implemented
properly. It was used only to disable stream, never enabling it.
That was the root cause of the regression when we added support
for s_stream on tvp5150 driver.
With that, we can get rid of the changes on tvp5150 side,
e. g. changeset 47de9bf8931e ('[media] tvp5150: Fix breakage for serial usage').
Tested video output on em2820+tvp5150 on WinTV USB2 and
video and/or vbi output on em288x+tvp5150 on HVR 950.

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.
After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.
To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

The Terratec Cinergy T XS is a DVB-T receiver with no analog TV tuner.
This patch adds support for the cards carrying the mt2060 tuner; it's
unclear whether there are cards sold under the same name which use a
different tuner.
As long as there are no reports of such cards, and indeed as long as
there are no working drivers for them, we assume that the USB device
[0ccd:0043] is carrying the mt2060 tuner.

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/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

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
