Hauppauge HVR-975 is a hybrid, dual frontend, single tuner USB device.
It contains lgdt3306a and si2168 frontends and one si2157 tuner. The
lgdt3306a frontend is currently enabled. This creates the second
demodulator and attaches it to the tuner.
Enables lgdt3306a|si2168 + si2157

This symbol mismatch is handled by NULL'ing out the release

- commit 835d66173a38 ("media: lgdt3306a: Fix module count mismatch

A possible hardware bug was discovered when using CA addon hardware
attached to the ngene hardware, in that the TS input buffer much likely
will shift and thus become unaligned to 188 byte blocks (a full TS frame)
when things like CA module initialisation (which happens via differing
communication paths) take place. This causes the TS NULL removal in
tsin_exchange() to fail to detect this previously inserted data and thus
causes userspace applications to receive data they didn't sent beforehand
and ultimately cause troubles.
On driver load with an inserted CAM, buffers are fine at first (note that
the driver has to keep the communication running from/to the card by
inserting TS NULL frames, this is done in tsout_exchange() via
FillTSBuffer() - that data is simply sent back by the hardware):
offset | 0 1 2 3 4 5 .... 188 189 190 191 192 193 .... 376
data | 47 1f ff 10 6f 6f .... 47 1f ff 10 6f 6f .... 47
After a few seconds, the CA module is recognised and initialised, which is
signalled by
dvb_ca_en50221: dvb_ca adapter X: DVB CAM detected and initialised successfully
This is where the first shift happens (this is always four bytes), buffer
becomes like this:
offset | 0 1 2 3 4 5 .... 188 189 190 191 192 193 .... 376
data | 6f 6f 6f 6f 47 1f .... 6f 6f 6f 6f 47 1f .... 6f
Next, VDR, TVHeadend or any other CI aware application is started, buffers
will shift by even more bytes. It is believed this is due to the hardware
not handling control and data bytes properly distinct, and control data
having an influence on the actual data stream, which we cannot properly
detect at the driver level.
Workaround this hardware quirk by adding a detection for the TS sync byte
0x47 before each TS frame copy, scan for a new SYNC byte and a TS NULL
packet if buffers become unaligned, take note of that offset and apply
that when copying data to the DVB ring buffers. The last <188 bytes from
the hardware buffers are stored in a temp buffer (tsin_buffer), for which
the remainder will be in the beginning of the next hardware buffer (next
iteration of tsin_exchange()). That remainder will be appended to the
temp buffer and finally sent to the DVB ring buffer. The resulting TS
stream is perfectly fine, and the TS NULL packets inserted by the driver
which are sent back are properly removed. The resulting offset is being
clamped to 188 byte segments (one TS packet). Though this can result in
a repeated TS packet if the overall offset grows beyond this (and it
will grow only on CA initialisation), this is still way better than
unaligned TS frames and data sent to userspace that just isn't supposed
to be there.
This compensation can be toggled by the ci_tsfix modparam, which defaults
to 1 (enabled). In the case of problems, this can be turned off by setting
the parameter to 0 to restore the old behaviour.

Move the copy logic that will skip previously inserted TS NULL frames when
moving data to the DVB ring buffers into an own function. This is done to
not duplicate code all over the place with the following TS offset shift
fixup patch.
While we're touching this part of the code, get rid of the DEBUG_CI_XFER
debug-ifdeffery. This could be toggleable either by a Kconfig or a module
param, but in the end this will accidentally be enabled and cause lots
of kernel log messages, and such devel debug shouldn't be there anyway.

On some architectures such as arm64, siano chip based TV-tuner
USB devices are not recognized correctly due to coherent memory
allocation failure with the following error:

[ 683.652978] smsusb: probe of 1-1:1.0 failed with error -12
This is caused by dma_alloc_coherent(NULL, ...) returning NULL in
smscoreapi.c.
To fix this error, allocate the buffer memory for the USB devices
via kmalloc() and let the USB core do the DMA mapping and free.

Currently, if there's no CXD2099AR attached to any expansion connector of
the ngene hardware, it will complain with this on every module load:
cxd2099 1-0040: No CXD2099AR detected at 0x40
cxd2099: probe of 1-0040 failed with error -5
ngene 0000:02:00.0: CXD2099AR attach failed
This happens due to the logic assuming such hardware is always there and
blindly tries to attach the cxd2099 I2C driver. Rather add a probe
function (in ngene-cards.c with a prototype in ngene.h) to check for
the existence of such hardware before probing, and don't try further if
no CXD2099 was found.

addon modules/cards, namely the DuoFlex CT2 (CXD2837), ISDB-T (CXD2838),
C2T2 (CXD2843) and C2T2I (CXD2854). Since all these modules are equipped

Add support for STV0367+TDA18212 based DuoFlex CT addon modules. For this,
add a demod probe function and all necessary demod/tuner attach functions
which use existing auxiliary drivers (stv0367 and tda18212) to support
this hardware. As tda18212 is an I2C client driver, proper cleanup code
is added to the deregistration sequence in ngene-core. To not cause use-
after-free situations when there's a CXD2099 I2C client connected, which
is rather freed in ngene-core.c:cxd_detach(), add i2c_client_fe to struct
ngene_channel to keep track if the i2c_client was allocated by a frontend
driver, rather than the CI code paths. Also move the I2C access functions
to the top of the file and add the required read_regs() function for the
tda18212 ping to work.
This adds autoselection (if MEDIA_SUBDRV_AUTOSELECT) of the STV0367 demod
driver and TDA18212 tuner driver to Kconfig aswell.

According to the TODO file, this driver only landed in staging because of
the way device nodes and data transfers are handled. Besides that this way
(use of secX devices) has become sort of standard to date (ie. VDR
supports this literally since ages via the ddci plugin, TVHeadend received
this functionality lately, and minisatip being currently worked on
regarding this), most importantly this I2C client only driver isn't even
responsible for setting up device nodes, not for handling data
transfer and so on, but only serves as interface for the dvb_ca_en50221
subsystem, just like every other DVB card out in the wild, with hard-wired
or such flexible CA interfaces. And, it would even work with cards having
the cxd2099 controller hard-wired.
Also, this driver received quite some love and even is a proper I2C client
driver by now. So, as this driver acts as a EN50221 frontend device, move
it to dvb-frontends. There is no need to keep it buried in staging.
This commit also updates all affected Kconfig and Makefile's, and adds
MEDIA_AUTOSELECT depends to ddbridge and ngene.
