Mauro Carvalho Chehab 446aba663b [media] tveeprom: get rid of unused arg on tveeprom_hauppauge_analog()
tveeprom_hauppauge_analog() used to need the I2C adapter in
order to print debug messages. As it now uses pr_foo() facilities
since commit 6037b3ca28 ("[media] tveeprom: print log messages
using pr_foo()"), the first argument of the function is not
needed anymore.

So, get rid of it.

Andi Shyti 0f7499fddb [media] rc-main: assign driver type during allocation
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.

Mauro Carvalho Chehab 7c64691353 [media] bt8xx/dst: use a more standard way to print messages
This driver uses a weird, non-standard macro to print errors.
It allows hiding all messages, including error ones, with doesn't
seem a good idea.

Instead, replace it to pr_foo(), and, for error messages,
use pr_err().

The remaining messages were previouly classified as notice,
info or debug, but they all looked like debug messages.

So, add a dprintk() macro using the "verbose" modprobe
argument to select what will be displayed.

Mauro Carvalho Chehab 652fd6eaeb [media] bt8xx: don't break long lines
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+\"(.*)/) {
			$c2=$1;
			$next =~ s/\"\n$//;
			$n = expand($next);
			$funpos = index($n, '(');
			$pos = index($c2, '",');
			if ($funpos && $pos > 0) {
				$s1 = substr $c2, 0, $pos + 2;

Hans de Goede 5c915c6876 [media] bttv: Width must be a multiple of 16 when capturing planar formats
On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).

This turns out to be caused by max-width (924) not being a multiple of 16.

We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing
to do conversion, triggering the solid green window problem.

Mauro Carvalho Chehab 7e3e68bcfd [media] dvb_frontend: pass the props cache to get_frontend() as arg
Instead of using the DTV properties cache directly, pass the get
frontend data as an argument. For now, everything should remain
the same, but the next patch will prevent get_frontend to
affect the global cache.

This is needed because several drivers don't care enough to only
change the properties if locked. Due to that, calling
G_PROPERTY before locking on those drivers will make them to
never lock. Ok, those drivers are crap and should never be
merged like that, but the core should not rely that the drivers
would be doing the right thing.

Mauro Carvalho Chehab d647f0b70c [media] include/media: move driver interface headers to a separate dir
Let's not mix headers used by the core with those headers that

    mkdir include/media/drv-intf/

	include/media/exynos-fimc.h include/media/msp3400.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

Mauro Carvalho Chehab b5dcee225c [media] include/media: split I2C headers from V4L2 core
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;

This is a preparation for a change to the type of v4l2 timestamps.
v4l2_get_timestamp() is a helper function that reads the monotonic
time and stores it into a 'struct timeval'. Multiple drivers implement
the same thing themselves for historic reasons.

Changing them all to use v4l2_get_timestamp() is more consistent
and reduces the amount of code duplication, and most importantly
simplifies the following changes.

The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

there are some serious issues at the audio hook implementation.

They're not following what's specified at the DocBook:
	http://linuxtv.org/downloads/v4l-dvb-apis/vidioc-g-tuner.html#tuner-audmode

Basically, it was assuming that the audmode (V4L2_TUNER_MODE_foo)
is a variable with a bit maskk. However, it isn't.

The bitmask only applies to rxsubchans field (V4L2_TUNER_SUB_foo).

As the code is also too complex, and not all hooks were returning
both audmode and rxsubchans to a VIDIOC_G_TUNER, rewrite the
functions, in order to fix both for get and set tuner ioctls.

  ...

That solves several merge conflicts:
	Documentation/DocBook/media/v4l/subdev-formats.xml
	Documentation/devicetree/bindings/vendor-prefixes.txt
	drivers/staging/media/mn88473/mn88473.c
	include/linux/kconfig.h
	include/uapi/linux/media-bus-format.h

The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.

Benjamin Herrenschmidt c2d5a71064 media/bt8xx: Remove old powerpc cruft
The powerpc arch code enables PCI_COMMAND_MEMORY (and has done so for
more than 10 years at least !) on pci_enable_device() and the hackery
on the MMIO accessor is useless as well, our writel does everything
this driver should need.

Ondrej Zary 35655bf854 [media] bttv: Improve TEA575x support
Improve g_tuner and add s_hw_freq_seek and enum_freq_bands support for cards
with TEA575x radio.

This allows signal/stereo detection and HW seek to work on these cards.

Ondrej Zary 1b50037315 [media] bttv: Convert to generic TEA575x interface
Remove tea575x-specific code from bttv and use the common driver instead.

Only set_frequency is implemented (signal/stereo detection or seek would
require more changes to bttv).

It works fine on Video Highway Xtreme (it actually makes the radio usable as
it currently cannot be tuned properly).

Miro/Pinnacle is untested but seems to be simple and should work.

However, I don't understand the Terratec Active Radio Upgrade code. The HW
seems to need IOR, IOW and CSEL signals that were taken from ISA bus on
older cards (IOR and IOW directly and CSEL from some address decoder) and
are emulated here using GPIOs. But the code manipulating these signals in
bttv seems to be broken - it never asserts the IOR signal. If anyone has
this HW, please test if I got that right.

Hans Verkuil 21a7e0596a [media] media: drivers shouldn't touch debug field in video_device
The debug field in struct video_device is for internal use only and
drivers should mix that with their own debug module options.

It is handled by the V4L2 core and users can set it using
/sys/class/video4linux/<devX>/debug.

It has been deprecated for some time now, so it is time to remove it
completely from the drivers.

Hans Verkuil 90ca8bef90 [media] btcx-risc: move to bt8xx
The btcx-risc module is no longer used by other drivers except for bttv.
So move it from common to bt8xx and make it part of the bttv driver instead
of as a separate module.

This module should never have been a common module since most of the code
has always been bttv specific.

Hans Verkuil 872dfcfe82 [media] bttv/cx25821/cx88/ivtv: use sg_next instead of sg++
Never use sg++, always use sg = sg_next(sg). Scatterlist entries can
be combined if the memory is contiguous but sg++ won't know about that.

As far as I can tell cx88 and ivtv are really broken because of this,
and bttv and cx25821 are OK because vb1 doesn't combine scatterlist
entries.

But regardless, sg++ should never be used, only sg_next is safe.

David Härdeman 120703f9eb [media] rc-core: document the protocol type
Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

David Härdeman 2886f013c3 [media] bt8xx: fixup RC5 decoding
The bt8xx driver does RC5 decoding for Nebula digi hardware, but includes
some pointless limitations (both start bits must be one, the
device/address/system must be 0x00). Remove those limitations and update
the keymap to use the full RC5 scancode (fortunately the 0x00 address
means that this is perfectly backwards compatible).
