The CIMaX SP2 driver is a EN50221 CI controller I2C driver similar to the
cxd2099 driver. Move it's Kconfig block into the newly introduced CI
subsection.

The cxd2099 driver makes use of the Regmap I2C kernel API, thus add
"select REGMAP_I2C" to it's Kconfig block. Also, make it default "m" if
!MEDIA_SUBDRV_AUTOSELECT, just like every other dvb-frontend driver.
And, while at it, remove the hyphens around the help tag.

If I2C is present and it is module, the DVB core should also
be a module, otherwise build will now fail with:

There's a comment there at s82168 that it is wrong.
With firmware 4.0.11, sleep/resume works well without
need of download it every time. But firmware 4.0.19
needs to be downloaded again after sleep.

media: v4l2-subdev: get rid of __V4L2_SUBDEV_MK_GET_TRY() macro
The __V4L2_SUBDEV_MK_GET_TRY() macro is used to define
3 functions that have the same arguments. The code of those
functions is simple enough to just declare them, de-obfuscating
the code.
While here, replace BUG_ON() by WARN_ON() as there's no reason
why to panic the Kernel if this fails.

As warned by smatch:
drivers/media/i2c/s5c73m3/s5c73m3-core.c:268 s5c73m3_check_status() error: uninitialized symbol 'status'.
if s5c73m3_check_status() is called too late, time_is_after_jiffies(end)
will return 0, causing the while to abort before reading status.
The current code will do the wrong thing here, as it will still
check if status != value. The right fix here is to change
the logic to ensure that it will always read the status.

Hauppauge produced a revision of ImpactVCBe using an 888,
with a 25MHz crystal, instead of using the default third

Proper cx2388x chip type is detected in cx25840 probe, the clock
rate is untouched however in probe. The cx25840 only checks for
non default clock values for 888 and provides custom settings for
25MHz 888. This change ensures that cx23888 chips with default 50MHz
crystals will not get configured as if they have 25MHz crystals. A
cx23887 board will continue to be configured for 25MHz crystal as
there is no custom clock support included for it.

The cx25840 driver currently configures 885, 887, and 888 using
default divisors for each chip. This check to see if the cx23885
driver has passed the cx25840 a non-default clock rate for a
specific chip. If a cx23885 board has left clk_freq at 0, the
clock default values will be used to configure the PLLs.
This patch only has effect on 888 boards who set clk_freq to 25M.

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.

As all drivers using the cxd2099 are converted to handle attach/detach
the generic I2C client way, the static inline cxd2099_attach isn't
required anymore. Thus cleanup cxd2099.h from the remainders, the adr
struct member also isn't used anymore.

Report I2C_FUNC_I2C in .functionality() as well. The I2C interface can
handle this fine and even is required for all I2C client drivers that
utilise the regmap API which are used from within the ngene driver.
