[media] s5p-fimc: Redefine platform data structure for fimc-is
Newer Exynos4 SoC are equipped with a local camera ISP that
controls external raw image sensor directly. Such sensors
can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to
the ISP, which then feeds image data to the FIMCn IP. Thus
there can be two busses associated with an image source
(sensor). Rename struct s5p_fimc_isp_info describing external
image sensor (video decoder) to struct fimc_source_info to
avoid confusion. bus_type is split into fimc_bus_type and
sensor_bus_type. The bus type enumeration is extended to
include both FIMC Writeback input types.
The bus_type enumeration and the data structure name in the

This patch fixes regression introduced in commit
6319d6a002beb26631
'[media] fimc-lite: Add ISP FIFO output support'.
In case of a configuration where video is captured at the video node
exposed by the FIMC-LITE driver there is a following video pipeline:
sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node
In this situation s_stream() handler of the FIMC-LITE.n is called
back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video
node, through vb2_stream_on/off(), start/stop_streaming and
fimc_pipeline_call(set_stream). The fimc->lock mutex is already held
then, before invoking vidioc_streamon/off. So it must not be taken
again in the s_stream() callback in this case, to avoid a deadlock.
This patch makes fimc->out_path atomic_t so the mutex don't need
to be taken in the FIMC-LITE subdev s_stream() callback in the DMA
output case.

be mapped to valid audmode. That didn't happen here.
Note that tuner drivers might decide to limit the possible audmode even

[media] omap3isp: preview: Lower the crop margins
The preview engine includes filters that consume columns and lines as
part of their operation, thus resulting in a cropped image. To allow
turning those filters on/off during streaming without affecting the
output image size, the driver adds additional cropping to make the total
number of cropped columns and lines constant regardless of which filters
are enabled.
This process needlessly includes the CFA filter, as whether the filter
is enabled only depends on the sink pad format, which can't change
during streaming.
Exclude the CFA filter from the preview engine margins.

[media] mb86a20s: add CNR measurement
Add Signal/Noise ratio measurement. On this device, a global measure
is taken by the demod. It also provides per-layer CNR measurements,
based on Modulation Error measures (MER).

[media] mb86a20s: add BER measurement
Add the methods to read bit error/bit count measurements from
mb86a20s. On ISDB-T devices, those reads are done per layer.
However, as userspace applications may not be aware of that,
add a global measure that will sum the bit errors and bit
counts for each layer, storing them into a global value.

[media] mb86a20s: calculate statistics at .read_status()
Instead of providing separate callbacks to read the several FE
stats properties, the better seems to use just one method that will:
- Read lock status;
- Read signal strength;
- if locked, get TMCC data;
- if locked, get DVB statistics.
As the DVB frontend thread will call this read_status callback
on every 3 seconds, and userspace can even call it earlier,
all stats data and layers layout will be updated together if
available, with is a good thing.

[media] dvb: the core logic to handle the DVBv5 QoS properties
Add the logic to poll, reset counters and report the QoS stats
to the end user.
The idea is that the core will periodically poll the frontend for
the stats. The frontend may return -EBUSY, if the previous collect
didn't finish, or it may fill the cached data.
The value returned to the end user is always the cached data.

[media] dvb: Add DVBv5 statistics properties
The DVBv3 statistics parameters are limited on several ways:
- It doesn't provide any way to indicate the used measure,
so userspace need to guess how to calculate/use it;
- Only a limited set of stats are supported;
- Can't be called in a way to require them to be filled
all at once (atomic reads from the hardware), with may
cause troubles on interpreting them on userspace;
- On some OFDM delivery systems, the carriers can be
independently modulated, having different properties.
Currently, there's no way to report per-layer stats.
To address the above issues, adding a new DVBv5-based stats API.
While here, correct inner code nomenclature on a few places.

TRY_EXT_CTRLS is unchanged and the error_idx field must always be set to
the failed control index in that case.
