10e712064b media: rc: update sunxi-ir driver to get base clock frequency from devicetree
This patch updates the sunxi-ir driver to set the base clock frequency from
devicetree.

This is necessary since there are different ir receivers on the
market, that operate with different frequencies. So this value could be
set if the attached ir receiver needs a different base clock frequency,
than the default 8 MHz.

78c4e08201 media: ngene: use common DVB I2C client handling helpers
Like in ddbridge, get rid of all duplicated I2C client handling constructs
and rather make use of the newly added dvb_module_*() helpers. Makes
things more clean and removes the (cosmetic) need for some variables.

The check on a valid ptr on ci->en isn't really needed since the cxd2099
driver will set	it at a	time where it is going to return successfully
from probing.

c966453b13 media: ddbridge: use common DVB I2C client handling helpers
Instead of keeping duplicated I2C client handling construct, make use of
the newly introduced dvb_module_*() helpers. This not only keeps things
way cleaner and removes the need for duplicated I2C client attach code,
but even allows to get rid of some variables that won't help in making
things look cleaner anymore.

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.

60d0bbec59 media: ngene: compensate for TS buffer offset shifts
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.

e5fc6767ea media: ngene: move the tsin_exchange() stripcopy block into a function
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.

564246fd3f media: siano: Fix coherent memory allocation failure on arm64
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:

[  663.556135] usbcore: deregistering interface driver smsusb
[  683.624809] smsusb:smsusb_probe: board id=18, interface number 0
[  683.633530] smsusb:smsusb_init_device: smscore_register_device(...) failed, rc -12

[  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.
