Several people reported unreliable reception with the current driver.
Furthermore, STR and SNR values seem to be inverted.
This fix is based on a patch posted by Hartmut Hackman.
Thanks to Helmut Auer for testing and helping to optimize the patch.
tda826x:
- set baseband cut-off to 19 MHz
tda10086:
- change the parameters of the carrier recovery loop
- toggle register 0x02 between 0x35 (tuning) and 0x00 (locked)
- invert STR and SNR values

This shrinks the size of "struct i2c_client" by 40 bytes:
- Substantially shrinks the string used to identify the chip type
- The "flags" don't need to be so big
- Removes some internal padding
It also adds kerneldoc for that struct, explaining how "name" is really a
chip type identifier; it's otherwise potentially confusing.
Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name
and for i2c_adapter.name, this needed to affect i2c_adapter too. The
adapters which used that symbol now use the more-obviously-correct
idiom of taking the size of that field.
JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to
avoid wasting space in padding.

When the tuner is attached, the tda10046 is not initilized yet, so it
is searching for its firmware. If the tuner is attached to the tda10046
silent i2c port, a bus collision can occur. Now the version is probed
during the first init or sleep call.

The dvb-pll sleep function could only send a 2-byte sequence to the PLL.
This isn't enough in some cases, for example fmd1216me will need to send
a 4-byte command to set both BB and AB to the correct values.
Instead of using a fake band with a frequency of 0 to store the sleep
data (which has room for only two bytes), the new sleep function works
like the init function. A new pointer is added to the pll description,
and when non-NULL points to a buffer with the length and data to send.

Some PLLs had one half the step size added to the offset, so that the
divisor would be rounded to the nearest integer. Some didn't and so
would always be rounded down.
This makes dvb-pll round to the nearest when calculating the divisor,
without the offset needing to be fudged. PLLs that had a fudged offset
have the offset changed to be just the IF frequency.
The satellite PLL dvb_pll_philips_sd1878_tda8261 was rounding up for some
reason, and I've kept it that way.
In addition, frequencies that were rounded to the nearest kHz are
extended to full Hz resolution. One sixth MHz step sizes that were
listed as 166,666 Hz are changed to 166,667 Hz, which is slightly closer.
PLLs that were already rounding:
dvb_pll_tda665x, offset was 36 1/6 (to nearest kHz) + step/2
dvb_pll_fmd1216me, offset was 36 1/8 (to two digits) + step/2
dvb_pll_thomson_fe6600, offset was 36 1/8 (to two digits) + step/2
dvb_pll_env57h1xd5, offset was 36 1/8 + step
Note that the last PLL, dvb_pll_env57h1xd5, appears to have had a bug in
the offset. Rather than adding stepsize/2, it was adding a full
stepsize. The PLL definition originally came from the dibusb driver,
which used 36 1/8 + step/2. The change to 36 1/8 + step was probably a
mistake added when the tuner was converted to dvb-pll.

The code the i2c transactions was leftover from the old V4L-based ATSC
driver. It did too little with too much code. It is re-written to
remove unnecessary parameters and be more efficient. A demod register
can now be read with one function call, instead of repeating a dozen line
block of code each time.
There were msleep()'s, which appear to be unnecessary, spread around all
the I2C transactions. These have been removed. Reading SNR used to take
about 130 ms, now it's down to 1.8 ms.
Reads from the demodulator's registers do not return correct results
sometimes. Adding or removing the delays in the I2C transactions did not
appear to effect the probability of failure. If anything, the
transactions without delays were less likely to fail, but since far more
transactions could be made per second the number of failures per hour was
greater.
To increase reliability, the SNR and get_params functions will now retry
once if they get bad data back. This appears to have reduced the
probability of failure to effectively zero.
Some error messages are cleaned up or given KERN_* levels when they were
missing.
or51132_setmode() wasn't returning correct error codes, which is fixed as
well.

The code of the dvb-pll driver and the lgh06xf driver is nearly
identical. The main difference is that the lgh06xf driver would set the
AGC TOP value on every tune call. The dvb-pll driver now has the ability
to set the AGC TOP when the front-end device is opened, which is a better
way to go about it. By using this ability of dvb-pll, the lgh06xf driver
is made unnecessary.
There is one other difference. dvb-pll will probe for the presence of an
I2C pll chip by doing a one byte read, the lgh06xf driver did not do
this. In some devices the PLL is not reachable over I2C at the timer the
tuner is attached. Some more initialization, such as firmware loading,
must take place first. None of the devices using a LG-H06xF should have
this problem.

Some tuners need or benefit from initialization, to change certain
settings from their power on default values.
Typically, tuners with TUA603x PLLs can benefit from setting the AGC TOP
value to something else. This patch includes code to set the AGC TOP to
103 dBuV for the Thomson DTT-761x tuners, which I have experimentally
verified gives the best SNR readings, increasing SNR by about 0.19 dB
over the default value.
Other tuners can make use of this as well. For example, the separate LG
TDVS-H06xF driver's only difference from dvb-pll is this same setting of
AGC TOP value.

A number of drivers selected DVB_PLL when they did not need it, and some
that did need it did not select it.
The DVB_PLL option is given a name and help text, so that it will show up
in the config menu. DVB_PLL support can be turned on if an out-of-tree
driver needs it.
The standard dvb fe customization support is added to dvb-pll.h. Since
all modules which select DVB_PLL do so unconditionally, it is not
possible to turn dvb-pll off when an enabled module selects it, unlike
most of the other frontend/tuner drivers. This is because the users of
dvb-pll have static references to dvb-pll symbols other than the attach
function. If these references are removed, then dvb-pll will be
disablable as the other frontend/tuner drivers are.

There are the following changes:
- separate configuration of IF and GPIOs.
- set GPIOs before firmware load. This helps to avoid I2C address
collisions.
- if desired invert GPIOs at sleep (automatic return to analog mode of card).
- added 3 tuner configuration bytes to config stuct.
- added i2c gate address to config struct.
- moved _state struct declaration to header file to make it accessible
on board layer.
- added "conf_probed" to the state struct to allow i.e. probing for correct
tuner version.
- changed firmware load mechanism to always:
+ check if already loaded
+ try to boot from eeprom
+ try downlad from host
- corrected name of tda10046 firmware image (backward compatible).
