Register saa7134 at the media controller core and provide
support for both analog TV and DVB.
Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
The saa7134_input.tv field was used to indicate if an input had
a RF signal for TV input. This is not needed anymore, as the input
type can be checked directly by the driver.
Also, due to a past bug when setting the TV standard at the
demod, all inputs should have this field set, with is wrong.
This reduces the size of the saa7134_boards by about 8KB,
on i386 (and probably twice on 64 bits), with is a nice
colateral effect:

It doesn't make any sense to only update the TV standard for TV,
as composite and S-Video inputs also need it.
Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
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.

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).

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

Converting debug prints to use pr_foo() is not trivial, as the
result will be a way worse than what's provided here, due to the
pieces of the code that prints the I2C transfers. Those use a
lot pr_cont(), and, depending on using either level 1 or 2,
a different set of macros are selected.
So, let's replace d1printk() and d2printk() macros by i2c_dbg()
and i2c_count() adding a debug level there.

On media drivers, debugging messages should be grouped into
categories, as this makes easier to debug the driver.
In the case of saa7134, the core has 2 debug categories, one
for IRQ, and another one for the core itself. The IRQ have
actually 2 levels of debug.
So, instead of using pr_dbg(), where everything would be in
the same box, let's define two macros that use pr_fmt(),
one for the core, and another one for irq.
With that, we can replace the remaining printk() occurrences
at the core to use either core_dbg() or irq_dbg(), depending
on the group of debug macros that need to be enabled.
