The dvb-pll code should do the same thing that
alps_tdee4_stv0297_tuner_set_params() was doing. Except the dvb-pll code
will check for tuner presence when attaching, while the old code didn't.
This tuner appears to not be behind the stv0297's I2C gate but is instead
on a different I2C adapter provided by the flexcop chip. The old code
would turn the I2C gate off each time the tuner was used. I've changed it
to turn the gate off when the tuner is attached and then disable the gate
control function. This should result in the gate staying off, which should
be even better.

The code in skystar23_samsung_tbdu18132_tuner_set_params() and
samsung_tbmu24112_tuner_set_params() is equivalent to what the dvb-pll code
does. There could be an issue because the dvb-pll code will probe to check
for the tuner, while the previous code didn't do any checks.

A recent patch didn't take into account that frontends can be compiled into
the kernel. Or that frontends compiled as modules can't be used by the
b2c2 driver if it is not a module itself.
Some frontends require multiple drivers, e.g. a demod driver and a tuner
driver. The code for the frontend support was getting added if the demod
driver was available. Change this to also require any needed tuner or SEC
drivers as well.

Changeset 1589a993f0 broke user visible
names of flexcop-pci devices, as it did reorder the enum of card types,
but did not adjust the array containing the card names.
Reorder the names, and uses [FC_AIR_DVBT] = "Air2PC/AirStar 2 DVB-T"
assignment style for more clarity.
It also adds the revision Number to the name for SkyStar rev. 2.3 and rev 2.6
as I think it is useful to see in log output.

The frontend attachment code didn't handle cases where the frontend
partially failed to attach. For instance, when the demod was attached
successfully but the tuner driver wasn't compiled or fails to init for some
reason. In these cases we try to clean up the partial attachment and fail
instead of proceeding with a broken frontend.
If frontend registration fails, clean up with dvb_frontend_detach() rather
than just calling the frontend's main release method. The former does some
additional stuff, like release an attached tuner and take care of putting
symbols when dynamic binding is used.
In skystar2_rev23_attach() it's not necessary to set fc->dev_type, that
gets set before skystar2_rev23_attach() is called.

With (some) Technisat cards you cannot run multiple DVB applications
in parallel and switch the channel at the same time.
There seems to be a problem on the interfaces or even inside the flexcop-device
that can't handle interruption on the streaming interface.
This patch adds a watchdog to check whether data is supposed to come in
(streaming PIDs are requested) and if no data is seen within 400ms (default) it
resets the streaming/pid-filtering hardware.
This patch is urgently needed to support the rev 2.8 of the hardware and solves
problem occassionally seen on older hardware.

Fixed trivial IPv4/6 address printing conflicts in fs/cifs/connect.c due
to the conversion to %pI (in this networking merge) and the addition of
doing IPv6 addresses (from the earlier merge of CIFS).
When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.
This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.
This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.
The patch were generated by this small script:
for i in `find drivers/media -name Kconfig`; do
cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
mv a $i
done
Also, manually reordered the tuner entries.

At some point the Flexcop driver was changed to support newer Flexcop cards.
These modifications however broke the detection of Cablestar 2 DVB-C cards.
The reason is that the earlier version of the driver used to retry
unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297)
seems to be very dependent on these retries and adding them back fixes
Cablestar detection.
This patch restores this behaviour for the CableStar2.

Different backends have different input busses (saa7146, flexcop).
To reflect that a config-option to the s5h1420-driver was added which makes
the output mode selectable.
Furthermore the s5h1420-driver is now doing the same i2c-method as it was done
before adding support for other i2c-users.
This patch needs to go into the current release of the kernel, as this driver
is currently broken.

b2c2-flexcop, dvb/bt8xx and video/bt8xx fails to build on ARM with:
__bad_udelay is specifically designed on ARM to fail when udelay is
called in a bad way. arch/arm/include/asm/delay.h has this to say
about __bad_udelay:
/*
* This function intentionally does not exist; if you see references to
* it, it means that you're calling udelay() with an out of range value.
*
* With currently imposed limits, this means that we support a max delay
* of 2000us. Further limits: HZ<=1000 and bogomips<=3355
*/
extern void __bad_udelay(void);
Solution is to replace udelay by a mdelay and udelay with value less than 2000
