Mauro Carvalho Chehab 06eeefe8e3 [media] media drivers: annotate fall-through
Avoid warnings like those:

drivers/media/pci/ddbridge/ddbridge-core.c: In function 'dvb_input_detach':
drivers/media/pci/ddbridge/ddbridge-core.c:787:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (input->fe) {
      ^
drivers/media/pci/ddbridge/ddbridge-core.c:792:2: note: here
  case 4:
  ^~~~
...

On several cases, it is just that gcc 7.1 is not capable of
understanding the comment, but on other places, we need an
annotation.

Bhumika Goyal f558461335 [media] saa7134: constify nxt200x_config structures
Declare nxt200x_config structures as const as they are only passed as
an argument to the function dvb_attach. dvb_attach calls its first
argument on the rest of its arguments. The first argument of
dvb_attach in the changed cases is nxt200x_attach and the parameter of
this function to which the object references are passed is of type
const. So, nxt200x_config structures having this property can be made
const.

tveeprom_hauppauge_analog() used to need the I2C adapter in
order to print debug messages. As it now uses pr_foo() facilities

needed anymore.

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.

Maciej S. Szmigiero 5a91206ff0 [media] saa7134: fix warm Medion 7134 EEPROM read
When saa7134 module driving a Medion 7134 card is reloaded reads of this
card EEPROM (required for automatic detection of tuner model) will be
corrupted due to I2C gate in DVB-T demod being left closed.
This sometimes also happens on first saa7134 module load after a warm
reboot.

Fix this by opening this I2C gate before doing EEPROM read during i2c
initialization.

Mauro Carvalho Chehab 395eff951a [media] saa7134: 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.

Sean Young 2ceeca0499 [media] rc: split nec protocol into its three variants
Currently we do not know what variant (bit length) of the nec protocol
is used, other than from guessing from the length of the scancode. Now
nec will be handled the same way as the sony protocol or the rc6 protocol;
one variant per bit length.

In the future we might want to expose the rc protocol type to userspace
and we don't want to be introducing this world of pain into userspace
too.

Mauro Carvalho Chehab 8fc3486783 [media] saa7134: use input types, instead of hardcoding strings
Currently, the saa7134 driver is hardcoding input names on each
board entry. More modern drivers define, instead, an enum for each
input type.

While the current logic works, it adds extra complexity at the driver,
as it needs to discover the type of the input using some euristics.

Instead, let's standardize the input types and use a type, instead of
a name on all places.

That will allow further patches to properly report the input type
via VIDIOC_G_INPUT and to remove an extra field from the struct to
identify if the input is for TV.

Please notice that several boards define an input for receiving composite
signals via a S-Video connector. The name of such input was inconsistent,
so this patch cleans it and make it to be properly reported the
same way for all boards.

Hans Verkuil df9ecb0cad [media] vb2: drop v4l2_format argument from queue_setup
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).

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$j\2\3,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done";
	);
	echo "Handling documentation..." >&2;
	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
	(
		cd include/$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;

of v4l2_plane.
struct vb2_plane {
        <snip>

        } m;
        unsigned int            data_offset;
}

Replace v4l2_buf with new member variables - index, type, memory - which
are common fields for buffer management.
struct vb2_buffer {
        <snip>
        unsigned int            index;
        unsigned int            type;

};

v4l2 specific fields - flags, field, timestamp, timecode,

Mauro Carvalho Chehab 816de50d35 [media] saa7134: fix page size on some archs
On some archs, like tile, the PAGE_SIZE is not 4K. In the case
of tile arch, it can be either 16KB or 64KB.

Due to that, a warning is produced:
	drivers/media/pci/saa7134/saa7134.h:678:43: warning: large integer implicitly truncated to unsigned type [-Woverflow]

This is actually an error, as it will write trach to the DMA size
registers. The logic at saa7134-ts already does the right thing:

	saa_writeb(SAA7134_TS_DMA0, ((dev->ts.nr_packets-1)&0xff));
	saa_writeb(SAA7134_TS_DMA1, (((dev->ts.nr_packets-1)>>8)&0xff));
	/* TSNOPIT=0, TSCOLAP=0 */
	saa_writeb(SAA7134_TS_DMA2,
		((((dev->ts.nr_packets-1)>>16)&0x3f) | 0x00));

So, fix the driver to take larger page sizes into account.

Mauro Carvalho Chehab 0df289a209 [media] dvb: Get rid of typedev usage for enums
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:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

Mauro Carvalho Chehab 6be5b1a19a [media] saa7134: change the debug macros for IR input
Rename the macros to input_dbg() and ir_dbg(), using pr_fmt()
on both, to be coherent with the other debug macro changes.

The ir_dbg() also prints the IR name.

I'm not sure if it is a good idea to keep both macros here,
but merging them would require tests on different flavors of
saaa7134-based boards.

So, for now, let's keep both.
