a689e3657d [media] dvb-core: add support for a DVBv5 get_frontend() callback
Creates a DVBv5 get_frontend call, renaming the DVBv3 one to
get_frontend_legacy(), while not all frontends are converted.

After the conversion for all drivers, get_frontend_legacy()
will be removed.

bc9cd2736b [media] Rename set_frontend fops to set_frontend_legacy
Passing DVBv3 parameters to set_frontend is not fun, as the
core doesn't have any way to know if the driver is using the
v3 or v5 parameters. So, rename the callback and add a new
one to allow distinguish between a mixed v3/v5 paramenter call
from a pure v5 call.

After having all frontends to use the new way, the legacy
call can be removed.

14d24d148c [media] tuners: remove dvb_frontend_parameters from set_params()
This is a big patch, yet trivial: now that all tuners use the DVBv5
way to pass parameters (e. g. via fe->dtv_property_cache), the
extra parameter can be removed from set_params() call.

After this change, very few DVBv3 specific stuff are left at the
tuners.

2e4e98e788 V4L/DVB: drivers/media: Make static data tables and strings const
Making static data const avoids allocation of additional r/w memory and
reduces initialisation time.  It also provides some additional opportunities
for compiler optimisations.

7638699c25 V4L/DVB: lgs8gxx: remove firmware for lgs8g75
The recently added support for lgs8g75 included some 8051 machine code
without accompanying source code.  Replace this with use of the
firmware loader.

Compile-tested only.

3ab1b9cecd V4L/DVB: lgs8gxx: Use shifts rather than multiply/divide when possible
If val is a u64, then following:

	val *= (u64)1 << 32;
	val /= (u64)1 << 32;

should surely be better represented as:

	val <<= 32;
	val >>= 32;

Especially as, for the division, the compiler might want to actually do a
division:

drivers/built-in.o: In function `lgs8gxx_get_afc_phase':
drivers/media/dvb/frontends/lgs8gxx.c:250: undefined reference to `__udivdi3'
