Raise the DVB frontends one level up, as the intention is to remove
the drivers/media/dvb directory.

Now that this field is deprecated, and core generates it for
DVBv3 calls, remove it from the drivers.
It also adds .delsys on the few drivers where this were missed.

Just like set_frontend, use the dvb cache properties for get_frontend.
This is more consistent, as both functions are now symetric. Also,
at the places get_frontend is called, it makes sense to update the
cache.
Most of this patch were generated by this small perl script:
while (<>) { $file .= $_; }
if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) {
my $get = $1;
$file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g;
}
print $file;
Of course, the changes at dvb_frontend.[ch] were made by hand,
as well as the changes on a few other places, where get_frontend()
is called internally inside the driver.
On some places, get_frontend() were just a void function. Those
occurrences were removed, as the DVB core handles such cases.

As all parameters are passed via DVBv5 to the frontends, there's
no need to pass them again via fops. Also, most drivers weren't using
it anyway. So, instead, just pass a parameter to indicate if the
hardware algorithm wants the driver to re-tune or not.

Instead of using dvb_frontend_parameters struct, that were
designed for a subset of the supported standards, use the DVBv5
cache information.
Also, fill the supported delivery systems at dvb_frontend_ops
struct.

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.

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.

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.

Detection class I2C_CLASS_TV_DIGITAL is set by many adapters but no
I2C device driver is setting it anymore, which means it can be
dropped. I2C devices on digital TV adapters are instantiated
explicitly these days, which is much better.

Hi there!
While having a look at the allocation of struct dvb_frontend in *_attach
functions, I found some cases calling memset after kzalloc. This is
redundant, and the attached patch removes these calls.
I also changed one case calling kmalloc and memset to kzalloc.
Regards

Some DVB drivers are incorrectly assuming that the size of
i2c_adapter.name is I2C_NAME_SIZE. Here's a fix.
Also change strncpy to strlcpy, as the former is error-prone (and was
indeed incorrectly used.)

To support a new device based on CX24123 (using the CX24113-tuner) the following was done:
- added two parameters to de-select the internal PLL-driver (for CX24108) and a AGC-function callback.
- added a virtual i2c-adapter which allow simple access behind the i2c-gate
- cleanup up some code

geniatech cards on Kworld
1) It sets LNBDCPol differently based on the card type. Now it should
work properly for both the kworld and geniatech cards.
2) It stops returning an error for the SEC_VOLTAGE_OFF voltage command
(the cx88-dvb level handles the actual voltage on/off, but it still
passes the ioctl down to the cx24123 level, which previously rejected
the OFF as invalid so the ioctl would report failure)

pointer field inside dvb_frontend
The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
always, before you could assign the static pointer directly, which was
dangerous.

- fixed the reception of channels with low symbol rates.
( The VGA1 and VGA2 offsets recommended by cx24109 docs for
symbol rates from 1 to 5 MSps do not work. I changed them
to values found experimentally. The charge pump current
and FILTUNE voltage are now set to values recommended in
the docs. This improves reception for symbol rates < 15 MSps.
The values written in the SYSSymbolRate registers are calculated
with better precision. )
- fixed the cx24123_get_fec() function. It was returning the values
for DCII mode.

Nova-S Plus (CX23883/CX24123/CX24109), without the Intersil ISL6421,
which is used for LNB control.
- LNB voltage and tone are controled by LNBDC and LNBTone bits from
register 0x29 of the CX24123 demodulator.
- The MO_GP0_IO register from CX23883 is used to turn LNB power on and off.
