This patch adds the Kconfig and Makefile for the c8sectpfe driver
so it will be built. It also selects additional demodulator and tuners
which are required by the supported NIM cards.

This patch adds support for the following 2 NIM cards: -
1) B2100A (2x stv0367 demods & 2x NXP tda18212 tuners)
2) STV0903-6110NIM (stv0903 demod + 6110 tuner, lnb24)

A NIM card is a cold plugable expansion card which usually
features a demodulator / tuner combination.

These functions are used by the core code for creating the LDVB
devices and adapter.

Addtionally some older SoC's (and potentially newer ones) have different
frontend HW which would allow those devices to be easily supported
in the future by keeping the code specific to the IP separate from the
more generic code.

This patch adds support for the c8sectpfe input HW found on
STiH407/410 SoC's.

It currently supports the TS input block, memdma engine
and hw PID filtering blocks of the C8SECTPFE subsystem.

The driver creates one LinuxDVB adapter, and a
demux/dvr/frontend set of devices for each tsin channel
which is specificed in the DT. It has been tested with
multiple tsin channels tuned, locked, and grabbing TS
simultaneously.

The B2100A dvb NIM card from ST has 2x stv0367 demodulators
and 2x TDA18212 silicon tuners, with a 16Mhz crystal. To
get this working properly with the upstream driver we need
to add support for the 16Mhz reference clock.

When using stv0367 demodulator with STi STB platforms,
we can have easily have four or more stv0367 demods running
in the system at one time.

As typically the b2120 reference design ships with a b2004a daughter
board, which can accept two dvb NIM cards, and each b2100A NIM
has 2x stv0367 demods and 2x NXPs tuner on it.

In such circumstances it is useful to print the i2c address
on error messages to know which one is failing due to I2C issues.

The Linux stack is short; we need to be able to count the number
of bytes used at stack on each function. So, we don't like to
use variable-length arrays, as complained by smatch:
        drivers/media/dvb-frontends/horus3a.c:57:19: warning: Variable length array is used.

The max usecase of the driver seems to be 10 bytes + 1 for the
register.

So, let's be safe and allocate 11 bytes for the write buffer.
This should be enough to cover all cases. If not, let's print

On built-in kernels this warning will always splat as this is part
of the module init. Fix that by shifting the PAT requirement check
out under the code that does the "quasi-probe" for the device. This
device driver relies on an existing driver to find its own devices,
it looks for that device driver and its own found devices, then
uses driver_for_each_device() to try to see if it can probe each of
those devices as a frambuffer device with ivtvfb_init_card(). We
tuck the PAT requiremenet check then on the ivtvfb_init_card()
call making the check at least require an ivtv device present
before complaining.

I noticed certain cards are currently under MEDIA_ANALOG_TV_SUPPORT

rather than TV receivers (with analog TV tuners).

MEDIA_CAMERA_SUPPORT maybe isn't the best name (only "meye" driver seems
to drive a real camera in a laptop) but it at least doesn't select the
TUNERs.

Perhaps the following patch would make sense.
