This device uses GPIOs: 28 to switch between analog and
digital modes: on digital mode, it should be set to 1.
The code that sets it on analog mode is OK, but it misses
the logic that sets it on digital mode.

Right now, media_device_pci_init and media_device_usb_init does
media_device allocation internaly. That preents its usage when
the media_device struct is embedded on some other structure.
Move memory allocation outside it, to make it more generic.

Except for the usbuvc driver (with has an embedded media_device
struct on it), the other drivers have a pointer to media_device.
On those drivers, replace their own implementation for the core
one. That warrants that those subdev drivers will fill the
media_device info the same way.

The output of a tuner is not only IF frequencies. They may also
output audio on some of its pins, and may even be a zero-IF tuner,
with outputs a baseband. So, rename the PAD name to make it
clearer and add a proper documentation about that at tuner.h.

Those are because the drivers are not properly checking if the

The media device node is registered and so made visible to user-space
before entities are registered and links created which means that the
media graph obtained by user-space could be only partially enumerated
if that happens too early before all the graph has been created.
To avoid this race condition, split the media init and registration
in separate functions and only register the media device node when
all the pending subdevices have been registered, either explicitly
by the driver or asynchronously using v4l2_async_register_subdev().
The media_device_register() had a check for drivers not filling dev
and model fields but all drivers in mainline set them and not doing
it will be a driver bug so change the function return to void and
add a BUG_ON() for dev being NULL instead.
Also, add a media_device_cleanup() function that will destroy the
graph_mutex that is initialized in media_device_init().

Entities should have one or more functions. Calling it as a
type proofed to not be correct, as an entity could eventually
have more than one type.
So, rename the field as function.
Please notice that this patch doesn't extend support for
multiple function entities. Such change will happen when
we have real case drivers using it.
No functional changes.

With the new API, a link can be either between two PADs or between an interface
and an entity. So, we need to use a better name for the function that create
links between two pads.
So, rename the such function to media_create_pad_link().

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/si476x.h include/media/soc_mediabus.h \
include/media/tea575x.h include/media/drv-intf/
And the references for those headers were corrected using:

Fix this compiler warning by allocating a structure to read the eeprom instead
of doing it on the stack and worse: the eeprom array is static, so that can
cause problems if there are multiple cx231xx instances.

I did consider removing the code altogether since the result is actually
not used at the moment, but I decided against it since it is used in other
drivers and someone might want to start using it in this driver as well. And
then it is useful that the code is already there.

changeset 5eeb3014827f added a fixup at the error check
code. However, it introduced a new error:
drivers/media/usb/cx231xx/cx231xx-cards.c:1586 cx231xx_usb_probe() error: we previously assumed 'dev' could be null (see line 1430)
This happens when dev = kmalloc() fails. So, instead of relying
on it to succeed, just change the parameter of clear_bit() from
'dev->devno' to 'nr'.

Commit b7085c086475 ("cx231xx: convert from pr_foo to dev_foo")
moves usb_get_dev(interface_to_usbdev(interface)) to the beginning
of cx231xx_usb_probe() to use udev->dev in dev_err(),
but it does not make sure usbdev is put on all failure paths.
Later dev_err(udev->dev) was replaced by dev_err(d).
So the patch moves usb_get_dev() below (before the first use)
and fixes another failure path.

Unfortunately, on devices that have multiple interfaces, udev->dev
points to the parent device (usb) instead of the cx231xx specific one.
Due to that the logs don't look too nice, as they'll print messages
as if they were produced by USB core:
usb-1-2: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces
Instead of using the name of the parent device, let's use the name
of the first cx231xx interface for all cx231xx sub-modules.
With this path, the logs will be nicer:
cx231xx 1-2:1.1: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces

There are several places at cx231xx that uses printk without
any special reason. Change all of them to use dev_foo().

Replace all pr_foo occurrences by dev_foo, as this is
the recommended way for drivers.

There are lots of debug printks printed with pr_info. Also, the
printk's data are not too coherent:
- there are duplicated driver name at the print format;
- function name format string differs from function to function;
- long strings broken into multiple lines;
- some printks just produce ugly reports, being almost useless
as-is.
Do a cleanup on that.
Still, there are much to be done in order to do a better printk
job on this driver, but, at least it will now be a way less
verbose, if debug printks are disabled, and some logs might
actually be useful.

It currently does just like what pr_foo() macros do. So,
replace them.
A deeper cleanup is needed, as there are lots of debug macros
printed with pr_info.

All switching should be done by i2c mux adapters.
Drop explicit dont_use_port_3 flag.
Drop info message about switch.
Only the removed code in start_streaming is questionable:
It did switch the port_3 flag without accessing i2c in between.

change almost all instances of I2C_1 to I2C_1_MUX_3
Only these cases are changed to I2C_1_MUX_1:
* All that have dont_use_port_3 set.
* CX231XX_BOARD_HAUPPAUGE_EXETER, old code did explicitly not switch to port3.
* eeprom access for 930C

This is a preparation for mapping I2C_1_MUX_1 and I2C_1_MUX_3 later to the seperate
muxed i2c adapters.
Map mux adapters to I2C_1 for now.
Add local variables for i2c_adapters in dvb_init to get line lengths
shorter.

Add support for:
[2040:b139] Hauppauge WinTV HVR-901H (1114xx)
According to the inf file, the hardware is similar to [2040:b131] Hauppauge WinTV 930C-HD (model 1114xx)
The only difference is the demod Si2161 instead of Si2165 (but both are
supported by the si2165 driver).

On some newer boards, like HVR-930C HD, the information at
the PCB tables are sometimes higher than the ones actually
available on the device. That causes the probing code to
