[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
board files are modified according to the above changes.

The previous method of registering platform entities into the main

Instead, we look up a device first and then check for its driver while
holding device lock.
The platform sub-devices are looked up and registered to the top

[media] s5p-fimc: fimc-lite: Prevent deadlock at STREAMON/OFF ioctls

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.

[media] tuner-core: map audmode to STEREO for radio devices

Fixes a v4l2-compliance error: setting audmode to a value other than mono
or stereo for a radio device should map to MODE_STEREO.
The spec specifies that for radio devices only mono and stereo audmodes are
valid. If the user specifies another audmode in v4l2_tuner, then that should
be mapped to valid audmode. That didn't happen here.
Note that tuner drivers might decide to limit the possible audmode even
further if it only supports mono. In that case the tuner driver can set
audmode to mono. However, that new value wasn't copied back to t->audmode,
and that has been fixed as well in this patch.

[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: Function reorder

Reorder functions to have everything related to stats/status read
close. That will make the file more organized as other stats
routines will be added.

No functional changes.

[media] mb86a20s: Split status read logic from DVB callback

Split the logic that reads the status from the DVB callback. That
helps to properly return an error code, if status read fails.

[media] mb86a20s: improve error handling at get_frontend

The read/write errors are not handled well on get_frontend. Fix it,
by letting the frontend cached values to represent the DVB properties
that were successfully retrieved.
While here, use "c" for dtv_frontend_properties cache, instead of
"p", as this is more common.

[media] uvcvideo: Set error_idx properly for S_EXT_CTRLS failures

The uvc_set_ctrl() calls don't write to the hardware. A failure at that
point thus leaves the device in a clean state, with no control modified.
Set the error_idx field to the count value to reflect that, as per the
V4L2 specification.
TRY_EXT_CTRLS is unchanged and the error_idx field must always be set to
the failed control index in that case.
