Allow specifying a custom std_map for tda18271 by external configuration.
This is required by cards that require custom std_map for analog TV or radio,
like AverMedia A706.

Add AverMedia AverTV Satellite Hybrid+FM (A706) card to saa7134 driver.
This requires some changes to tda8290 - disabling I2C gate control and
passing custom std_map to tda18271.
Also tuner-core needs to be changed because there's currently no way to pass
any complex configuration to analog tuners.

Allow disabling I2C gate handling by external configuration.
This is required by cards that have all devices on a single I2C bus,
like AverMedia A706.

config looks like a hack that was added to tuner-core to allow some
configuration of TDA8290 tuner (it's not used by any other driver).
But with the new configuration options of tda8290 driver (no_i2c_gate
and std_map), it's no longer sufficient.
Change config to be void * instead, which allows passing tuner-dependent
config struct to drivers.
Also update saa7134 driver to reflect this change (no other driver uses this).

I pushed patch 1 & 2 into the 'zary' branch of my 'dvb' git tree on
linuxtv.org -- I am going to do some testing and then issue a merge
request to Mauro if all is OK.
As for this patch, I think this is a good idea, but I think the patch
should be resent with RFC in the title, to ensure that everybody sees
that you're proposing a tuner internal API change (unless Mauro has
any comments in this thread)
I'm still digging a bit to make sure this doesn't have any negative
effect on the tda827x driver, but it looks safe to me right now.
I'd like to hear Mauro's comments on this too, but it looks good to me.

For the most part, this patch is fine and makes good sense to me.
However, instead of adding the option to the config structure, I think
you should just set the pointer to i2c_gate_ctrl to NULL from within
the bridge driver -- this is what other drivers do when they want to
disable a single function in the _ops struct.
I already pushed your patch as-is to the zary branch of my dvb tree on
linuxtv.org. If you want to push a new patch that incorporates my
suggestion above, then I'll replace the patch. Otherwise, you can
also just provide a separate patch against that tree to just remove
the config struct change and the NULL assignment in the attach().

It looks good to me, as it makes clearer for what purpose the config is being
used.
I would also change the magic values for LNA config to some enum, as
"0", "1", "2", "3" doesn't bring any meaning.
It would be better to call it with something like:
enum tda8290_lna {
TDA8290_LNA_OFF = 0,
TDA8290_LNA_GP0_HIGH_ON = 1,
TDA8290_LNA_GP0_HIGH_OFF = 2,
TDA8290_LNA_ON_BRIDGE = 3,
};
and replace the magic number occurrences at tda8290, tda827x and saa713x.

I don't see any other way to set i2c_gate_ctrl to NULL. saa7134 calls
s_type_addr and passes the config parameter. tuner-core finds that the tuner
type is TDA8290 and calls tda829x_attach which does tuner autodetecion.
i2c_gate_ctrl must be set to NULL before this or the detection will fail.

* [PATCH] tda8290: change magic LNA config values to enum

To: Mauro Carvalho Chehab; +Cc: Michael Krufky, linux-media
Use enum instead of magic values for LNA config in tda8290.
Update tda827x, tda18271 and saa7134 to use the enum too.

What's the status of this patch series?
The two tda8290 patches are in Michael's dvb tree.
I've sent an additional clean-up patch (on Mauro's suggestion) for the
tuner-core change.
I guess that the final AverMedia A706 patch would be easily merged once the
tda8290 and tuner-core changess are done.
Should I resend something?

I've just been a bit busier lately that I had foreseen, but no need to
resend anything - I have your patches. You'll hear back from me
shortly.
