7a6fbd8337 V4L/DVB (12294): b2c2: Use dvb-pll for Cablestar2
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.

016e53de0a V4L/DVB (12293): b2c2: Use dvb-pll for Skystar2 rev 2.3 and rev 2.6
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.

68b7f7616a V4L/DVB (12291): b2c2: fix frontends compiled into kernel
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

eccd15aad7 V4L/DVB (11964): b2c2: Fix problems with frontend attachment
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.

382c5546d6 V4L/DVB (10694): [PATCH] software IRQ watchdog for Flexcop B2C2 DVB PCI cards
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.

8b21c1e90e V4L/DVB (9885): drivers/media Kconfig's: fix bugzilla #12204
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.

11c6c7fb89 V4L/DVB (9781): [PATCH] Cablestar 2 I2C retries (fix CableStar2 support)
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.

options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a

Git changeset 6bdcc6e6db dropped the
stand-alone lgh06xf module, whose functionality was absorbed into the
dvb-pll module. However, there was a minor difference between the code
in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop
devices using the LG-H06xF NIM.

dvb-pll will probe for the presence of an i2c pll chip by performing a
single byte read, the lgh06xf driver did not do this. Unfortunately, the
code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads
as a probe.  Such probes with the current code will always fail.

In order to work around this problem, and restore proper functionality
of the Airstar HD5000 device, this hack was created to make the probe
appear to succeed.  The single byte read in dvb_pll_attach is the only
place where such a probe would ever occur, so this change is safe, and
will not affect any other devices.

Of course, if one knew how to actually perform the read operation, it
would be better to go that route.  In the meantime, however, we must
apply this workaround, in order to prevent the regression that causes
tuning to fail on the Airstar HD5000 ATSC device.

Thanks to Jarod Wilson, who had originally reported this regression, and
to Geoffrey Hausheer, whose original workaround patch led us to find the
actual cause of the problem.

72fb39ea58 V4L/DVB (5761): Fix broken b2c2 dependency on non x86 architectures
This patch moves flexcop-dma (currently used only by flexcop-pci) to
b2c2-flexcop-pci module, that is dependent on CONFIG_PCI, fixing the bug 
as reported by Geert Uytterhoeven <geert@linux-m68k.org>:

drivers/media/dvb/b2c2/flexcop-dma.c uses the PCI DMA API, but
DVB_B2C2_FLEXCOP doesn't depend on PCI, causing the following problem on
PCI-less systems:

| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'
| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'

Apparently this is the flexcop DMA core, which is used by both
DVB_B2C2_FLEXCOP_PCI and DVB_B2C2_FLEXCOP_USB.

2096b956d2 i2c: Shrink struct i2c_client
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.

6bdcc6e6db V4L/DVB (5363): Dvb: Remove lgh06xf driver
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.

76db93d03f V4L/DVB (4846): Create new lgh06xf atsc tuner module
This patch creates a new atsc tuner module for the LG TDVS-H06xF ATSC tuners,
called lgh06xf.  The purpose of this change is to reduce some duplicated
code, and to allow the lgh06xf tuner code to take advantage of dvb_attach().
As a side effect, the dependency of dvb-bt8xx on dvb-pll has been removed,
since the lgh06xf module itself will use dvb-pll, while remaining optional
for the dvb-bt8xx driver through the use of DVB_FE_CUSTOMISE
