Allow stepless synthesizer configuration. With that change we lose
precision a little bit, as it is now between +-500Hz from the target.
It could be better but on that case calculation algorithm goes more
complex and atm there is more important things to do.
Two approach to improve which comes to my mind are:
1) select and use biggest suitable step
2) use greatest common divisor algo to find divisor for thresh & frac
when possible to avoid rounding errors, which is root of cause of
current +-500Hz inaccuracy.

Each source entity maintains a pointer to the counterpart sink
entity while an enabled link connects them. It should be managed by

filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.

media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.

[media] media: lirc: Allow lirc dev to talk to rc device
The use case is simple, if any rc device has allowed protocols =
RC_TYPE_LIRC and map_name = RC_MAP_LIRC set, the driver open will be never
called. The reason for this is, all of the key maps except lirc have some
KEYS in there map, so during rc_register_device process these keys are
matched against the input drivers and open is performed, so for the case
of RC_MAP_EMPTY, a vt/keyboard is matched and the driver open is
performed.
In case of lirc, there is no match and result is that there is no open
performed, however the lirc-dev will go ahead and create a /dev/lirc0
node. Now when lircd/mode2 opens this device, no data is available
because the driver was never opened.
Other case pointed by Sean Young, As rc device gets opened via the
input interface. If the input device is never opened (e.g. embedded with
no console) then the rc open is never called and lirc will not work
either. So that's another case.
lirc_dev seems to have no link with actual rc device w.r.t open/close.
This patch adds rc_dev pointer to lirc_driver structure for cases like
this, so that it can do the open/close of the real driver in accordance
to lircd/mode2 open/close.
Without this patch its impossible to open a rc device which has
RC_TYPE_LIRC ad RC_MAP_LIRC set.
[media] media: rc: Add rc_open/close and use count to rc_dev
This patch adds user count to rc_dev structure, the reason to add this
new member is to allow other code like lirc to open rc device directly.
In the existing code, rc device is only opened by input subsystem which
works ok if we have any input drivers to match. But in case like lirc
where there will be no input driver, rc device will be never opened.
Having this user count variable will be usefull to allow rc device to be
opened from code other than rc-main.
This patch also adds rc_open and rc_close functions for other drivers
like lirc to open and close rc devices. This functions safely increment
and decrement the user count. Other driver wanting to open rc device
should call rc_open and rc_close, rather than directly modifying the
rc_dev structure.

[media] coda: add CODA7541 decoding support
This patch enables decoding of h.264 and mpeg4 streams on CODA7541.
Queued output buffers are immediately copied into the bitstream
ringbuffer. A device_run can be scheduled whenever there is either
enough compressed bitstream data, or the CODA is in stream end mode.
Each successful device_run, data is read from the bitstream ringbuffer
and a frame is decoded into a free internal framebuffer. Depending on
reordering, a possibly previously decoded frame is marked as display
frame, and at the same time the display frame from the previous run
is copied out into a capture buffer by the rotator hardware.
The dequeued capture buffers are counted to send the EOS signal to
userspace with the last frame. When userspace sends the decoder stop
command or enqueues an empty output buffer, the stream end flag is
set to allow decoding the remaining frames in the bitstream
ringbuffer.
The enum_fmt/try_fmt functions return fixed capture buffer sizes
while the output queue is streaming, to allow better autonegotiation
in userspace.
A per-context buffer mutex is used to lock the picture run against
buffer dequeueing: if a job gets queued, then streamoff dequeues
the last buffer, and then device_run is called, bail out. For that
the interrupt handler has to be threaded.

[media] ene_ir: Fix interrupt line passthrough to hardware
While we can delay IRQ intialization, we need the interrupt number
right away because unusually hardware have programable interrupt number,
and thus we give it the number that was allocated by BIOS

[media] staging: lirc: clean error handling in probe()
We have reorganized the error handling into a simpler and more canonical
format.
Additionally we removed extra empty lines, switched to devm_kzalloc(), and
substitute 'minor' by 'ret' in the igorplugusb_remote_probe() function.

[media] radio-aztech: Implement signal strength detection and fix stereo detection
Current stereo detection code is wrong - it reads TUNED bit instead of STEREO bit.
Fix that and implement signal strength detection too.
Also remove useless s_stereo functionn.

[media] radio-aztech: Convert to generic lm7000 implementation
Aztech radio card is based on LM7001 chip which is (software) compatible with LM7000.
So remove the LM7000-specific code from the driver and use generic code.
Also found that the card does not have A0..A2 ISA pins connected, which means that the region size is 8 bytes.

[media] bttv: stop abusing mbox_we for sw_status
Kodicom 4400R and Geovision GV-800 code in bttv driver abuses mbox_we (int)
in struct bttv as char *.
Remove this hack and add a proper sw_status array to struct bttv instead.
This is a a preparation to remove mbox_we.
