[PATCH v2 00/10] STV0910/STV6111 drivers, ddbridge CineS2 V7 support

[Daniel Scheller <d.scheller.oss@gmail.com>]

From: Daniel Scheller <d.scheller@gmx.net>

For Linux 4.14.

This series adds drivers for the ST STV0910 DVB-S/S2 demodulator ICs and
the ST STV6111 DVB-S/S2 tuners, and utilises them to enable ddbridge to
support the current line of Digital Devices DVB-S/S2 hardware (e.g. Cine
S2 V7/V7A adapters, DuoFlex S2 V4 addon modules and maybe more, with
similar components).

The two new drivers have been picked up from Digital Devices' vendor-
provided dddvb driver package, as of release 0.9.29. Permission to reuse
(and mainline) them was formally granted by Ralph Metzler
<rjkm@metzlerbros.de>.

Drivers have been cleaned up alot (formatting fixes, dead code removal,
features depending on not-yet-available API changes removed). Checkpatch
complaints left:

  WARNING: please write a paragraph that describes the config symbol fully
  #39: FILE: drivers/media/dvb-frontends/Kconfig:31:
  +config DVB_STV0910

Not sure what checkpatch demands, since a module description exists in
Kconfig... Applies to the stv6111 aswell.

  WARNING: added, moved or deleted file(s), does MAINTAINERS need updating?
  #64:
  new file mode 100644

See below.

  WARNING: 'VALIDE' may be misspelled - perhaps 'VALID'?
  #3314: FILE: drivers/media/dvb-frontends/stv0910_regs.h:1467:
  +#define FSTV0910_P2_NOSRAM_VALIDE  0xf30e0004

Picked from upstream. Since I'm not sure if this really is a mistake
(maybe the hardware vendor really wants to name the reg like this?) so
kept as-is.

CamelCase and ALLCAPS are changed into kernel_kase. Patches have been
proposed to the vendor driver package maintainers to keep things synced
as much as possible.

Patch 2 is a fix for an issue found while preparing this series for
posting, and was in parallel submitted to the vendor's GIT repository.

Adding myself to MAINTAINERS for stv0910 and stv6111 as I'll keep track
of any upstream (vendor provided package) changes and propose them
for mainline inclusion.

Mauro, I assume you're the one who reviews this (since these are new
drivers). It'd be very great to have this in for 4.14 to tackle the
ddbridge bump for 4.15. Of course awaiting review yet, this v2 should
be a good candidate for merge.

Changes from v1 to v2:
 - CamelCase and ALLCAPS changed to kernel_case
 - Signal statistics acquisition refactored to comply with standards
 - printk* and pr_* changed to dev_*
 - Add myself to MAINTAINERS for stv0910 and stv6111
