The customer PC hardware can be shipped with lots of different
configurations, as vendors use to replace some of the chips on
their hardware along the time. All drivers that support such
devices are prepared to handle the hardware differences, using
their own auto-probing logic.
They do it in a way that number of inputs and outputs for a given
hardware type doesn't change.
Now that we're adding media controller capabilities to those drivers,
we need to standardize the number of inputs and outputs for each
hardware type, as we want to have a generic function at the V4L2
core that would create the links for the entities that are expected
on such hardware.
Such standard is already there for tuners, but tuner.h is not the
best place to store such data, as we'll need to add definitions also
for analog TV demodulators.
Also, we'll need a place to put a set of MC handling functions. So,
let's create a v4l2-mc.h to store such kind of definitions.

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.
No functional changes.

Remove some bad whitespaces before tabs and fix the initial
comment to be compliant with Kernel coding style.
Now, the only complains are about long comment lines at the
defines. Those warnings should be ok to be kept.

This is part of the V4L2 core, so its kABI should be
documented at device-drivers DocBook.
Add the meta-tags for that.

config looks like a hack that was added to tuner-core to allow some
configuration of TDA8290 tuner (it's not used by any other driver).
But with the new configuration options of tda8290 driver (no_i2c_gate
and std_map), it's no longer sufficient.
Change config to be void * instead, which allows passing tuner-dependent
config struct to drivers.
Also update saa7134 driver to reflect this change (no other driver uses this).

This adds support for three Sony BTF tuners:
TUNER_SONY_BTF_PG472Z: PAL+SECAM
TUNER_SONY_BTF_PK467Z: NTSC-M-JP
TUNER_SONY_BTF_PB463Z: NTSC-M
These come from the go7007 staging driver where they were implemented in
the wis-sony-tuner i2c driver.
Adding support for these tuners to tuner-types.c is the first step towards
removing the wis-sony-tuner driver.

This is initial code written by Davide Ferri for the PCTV 340e, including
a new xc4000 driver. I am checking in all the code unmodified, and making
no assertions about its quality (other than confirming it compiles).

tda9887 used to use the T_STANDBY type internally, while tea5761
used it to put the device to sleep. Fix the code for it to work
properly with the tuner core changes and remove this flag from
tuner.h.

In the past, T_STANDBY were used on devices with a separate radio tuner to
mark a tuner that were disabled. With the time, it got newer meanings.
Also, due to a bug at the logic, the driver might incorrectly return
T_STANDBY to userspace.
So, instead of keeping the abuse, just use a boolean for storing
such information.
We can't remove T_STANDBY yet, as this is used on two other drivers. A
latter patch will address its usage outside tuner-core.
