This makes it easier to have outputs without subdevs.
This needs more work. The way the outputs are configured should be identical
to how inputs are configured.

vpif_capture relied on a 1-1 mapping of input and subdev. This is not
necessarily the case. Separate the two. So there is a list of subdevs
and a list of inputs. Each input refers to a subdev and has routing
information. An input does not have to have a subdev.
The initial input for each channel is set to the fist input.
Currently missing is support for associating multiple subdevs with
an input.

The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the
first containing interleaved JPEG/YUYV data and the second containing
meta data describing the interleaving method.
The image data is transferred with MIPI-CSI "User Defined Byte-Based
Data 1" type and is captured to memory by FIMC DMA engine.
The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image
Data" and it is captured in the MIPI-CSI slave device and copied to
the bridge provided buffer.
To make sure the size of allocated buffers is correct for the subdevs
configuration when VIDIOC_STREAMON ioctl is invoked, an additional
check is added at the video pipeline validation function.
Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved
from a sensor subdev.

MIPI-CSI has internal memory mapped buffers for the frame embedded
(non-image) data. There are two buffers, for even and odd frames which
need to be saved after an interrupt is raised. The packet data buffers
size is 4 KiB and there is no status register in the hardware where the
actual non-image data size can be read from. Hence the driver copies
whole packet data buffer into a buffer provided by the FIMC driver.
This will form a separate plane in the user buffer.
When FIMC DMA engine is stopped by the driver due the to user space
not keeping up with buffer de-queuing the MIPI-CSIS will still run,
however it must discard data which is not captured by FIMC. Which
frames are actually capture by MIPI-CSIS is determined by means of
the s_tx_buffer subdev callback. When it is not called after a single
embedded data frame has been captured and copied and before next
embedded data frame interrupt occurrs, subsequent embedded data frames
will be dropped.

As spotted by Dan Carpenter <dan.carpenter@oracle.com> (thanks!), we have
improperly used an unsigned variable in a calculation that may result in a
negative number. This may cause an unintended underflow if the interface
frequency of the tuner is > approx. 40MHz.
This patch should resolve the issue, following an approach similar to what is
used in af9013.c.

As em28xx-dvb will always be initialized asynchronously, there's

Fixes a known regression with kernel 3.6 with tda18271 driver

otherwise udev would give up of loading a firmware.

em28xx-dvb, em28xx-alsa and em28xx-ir are typically initialized
asyncrhronously. The exception for it is when those modules
are loaded before em28xx (or before an em28xx card insertion) or
when they're built in.
Make the extentions to always load asynchronously. That allows
having all DVB firmwares loaded synchronously with udev-182.
