This adds the frontend driver for the MaxLinear MxL5xx family of tuner-
demodulators, as used on Digital Devices MaxS4/8 four/eight-tuner cards.
The driver was picked from the dddvb vendor driver package and - judging
solely from the diff - has undergone a 100% rework:
- Silly #define's used to pass multiple values to functions were
expanded. This resulted in macro/register names not being usable
anymore for such occurences, but makes the code WAY more read-,
understand- and maintainable.
- CamelCase was changed to kernel_case
- All typedef were removed
- Overall code style was fixed, besides >80char lines in _defs.h and
_regs.h, checkpatch is happy.
- Also, signal stat acquisition was made to comply with the DVB API
ways to do these things.

This adds a frontend driver for the ST STV6111 DVB-S/S2 tuners. Like the
stv0910 demod frontend driver, this driver originates from the Digital
Devices' dddvb vendor driver package as of version 0.9.29, and was cleaned
up aswell. No functionality had to be removed though. Any camel case has
been converted to kernel_case, fixup patch has been proposed upstream.

This adds a multi frontend driver for the ST STV0910 DVB-S/S2 demodulator
frontends. The driver code originates from the Digital Devices' dddvb
vendor driver package as of version 0.9.29, and has been cleaned up from
core API usage which isn't supported yet in the kernel, and additionally
all obvious style issues have been resolved. All camel case and allcaps
have been converted to kernel_case and lowercase. Patches have been sent
to the vendor package maintainers to fix this aswell. Signal statistics
acquisition has been refactored to comply with standards.

The DVB binding schema at the DVB core assumes that the frontend is a
separate driver. Faling to do that causes OOPS when the module is
removed, as it tries to do a symbol_put_addr on an internal symbol,
causing craches like:

This patch adds support for the Technisat Skystar S2 - this
has been tried before but the cx24120 driver was a bit out of shape
and it didn't got any further:
https://patchwork.linuxtv.org/patch/10575/
It is an old card, but currently being sold off for next to nothing,
so it's proving quite popular of late. Noticing it's quite similar
to the cx24116 and cx24117 I've rewritten the driver in a similar way.
There were a few registers and commands from those drivers
missing from this one I've tested out and found they do something so
they've been added in to speed up tuning and to make get_frontend
return something useful.

This patch adds driver for tc90522 demodulator chips.
The chip contains 4 demod modules that run in parallel and are independently
controllable via separate I2C addresses.
Two of the modules are for ISDB-T and the rest for ISDB-S.
It is used in earthsoft pt3 cards.
Note that this driver does not init the chip,
because the initilization sequence / register setting is not disclosed.
Thus, the driver assumes that the chips are initilized externally
by its parent board driver before fe->ops->init() are called.
Earthsoft PT3 PCIe card, for example, contains the init sequence
in its private memory and provides a command to trigger the sequence.

Driver for the CIMaX SP2 common interface chip. It is very much based on
the existing cimax2 driver for cx23885, but should be more reusable. The
product has been sold with name Atmel T90FJR as well and the data sheets
for that chip seem to be publicly available.
It seems that the USB device that I have and the cx23885 based devices will
need to interact differently with the chip for the CAM operations. Thus
there is one callback function that is passed on to the sp2 driver
(see function sp2_ci_op_cam for that one).
IRQ functionality is not included currently (not needed by USB devices
and I don't have a PCIe device for development).

While here, standardize the usage of += on all cases where multiple
