The dequed CAPTURE_MPLANE type buffers don't contain the flags that the
originally queued OUTPUT_MPLANE type buffers have. This breaks compliance.
Copy the source v4l2_buffer flags to the destination v4l2_buffer flags before
they are dequed.

The vpe driver wasn't setting the correct field parameter for dequed CAPTURE
type buffers for the case where the captured output is progressive.
Set the field to V4L2_FIELD_NONE for the completed destination buffers when
the captured output is progressive.
For OUTPUT type buffers, a queued buffer's field is forced to V4L2_FIELD_NONE
if the pixel format(configured through s_fmt for the buffer type
V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE specifies) the field type isn't interlaced.
If the pixel format specified was V4L2_FIELD_ALTERNATE, and the queued buffer's
field isn't V4L2_FIELD_TOP or V4L2_FIELD_BOTTOM, the vb2 buf_prepare op returns
an error.
This ensures compliance, and that the dequeued output and captured buffers
contain the field type that the driver used internally.

The vpe output and capture queues are initially configured to default values in
vpe_open(). A G_FMT before any S_FMTs will result in these values being
populated.
The colorspace and bytesperline parameter of this initial configuration are
incorrect. This breaks compliance when as we get 'TRY_FMT(G_FMT) != G_FMT'.
Fix the initial queue configuration such that it wouldn't need to be fixed by

The minimum width and height for VPE input/output was kept as 128 pixels. VPE
doesn't have a constraint on the image height, it requires the image width to
be at least 16 bytes.
Change the minimum supported dimensions to 32x32. This allows us to de-interlace
qcif content. A smaller image size than 32x32 didn't make much sense, so stopped

The video_device struct is currently embedded in the driver data struct vpe_dev.
A vpe_dev instance is allocated by the driver, and the memory for the vfd is a
part of this struct.
The v4l2 core, however, manages the removal of the vfd region, through the
video_device's .release() op, which currently is the helper
video_device_release. This causes memory corruption, and leads to issues when
we try to re-insert the vpe module.
Use the video_device_release_empty helper function instead.

VPE has a ctrl parameter which decides how many mem to mem transactions the
active job from the job queue can perform.
The driver's job_ready() made sure that the number of ready source buffers are
sufficient for the job to execute successfully. But it didn't make sure if
there are sufficient ready destination buffers in the capture queue for the
VPE output.
If the time taken by VPE to process a single frame is really slow, then it's
possible that we don't need to imply such a restriction on the dst queue, but
really fast transactions(small resolution, no de-interlacing) may cause us to
hit the condition where we don't have any free buffers for the VPE to write on.
Add the extra check in job_ready() to make sure we have the sufficient amount
of destination buffers.

Exporting functions for hardware filter is a bad idea, as it
breaks compilation if:
CONFIG_DVB_USB_AF9035=y
CONFIG_DVB_AF9033=m
Because the PID filter function calls would be hardcoded at
af9035.
The same doesn't happen with af9033_attach() because the
dvb_attach() doesn't hardcode it. Instead, it dynamically
links it at runtime.
However, calling dvb_attach() multiple times is problematic,
as it increments module kref.
So, the better is to pass one parameter for the af9033 module
to fill the hardware filters, and then use it inside af9035.

This patch adds clock provider so the the SCLK_CAM0/1 output clocks
can be accessed by image sensor devices through the clk API.

This patch removes the common fimc-is-sensor driver for image sensors
that are normally controlled by the FIMC-IS firmware. The FIMC-IS
driver now contains only a table of properties specific to each sensor.
The sensor properties required for the ISP's firmware are parsed from
device tree and retrieved from the internal table, which is selected
based on the compatible property of an image sensor.
To use the Exynos4x12 internal ISP the S5K6A3 sensor driver (drivers/
media/i2c/s5k6a3.c) is now required.

This patch adds the V4L2 asynchronous subdev registration and
device tree support. Common clock API is used to control the
sensor master clock from within the subdev.

This patch adds subdev driver for Samsung S5K6A3 raw image sensor.
As it is intended at the moment to be used only with the Exynos
FIMC-IS (camera ISP) subsystem it is pretty minimal subdev driver.
It doesn't do any I2C communication since the sensor is controlled
by the ISP and its own firmware.
This driver, if needed, can be updated in future into a regular
subdev driver where the main CPU communicates with the sensor
directly.

In all cases, when the first capture is called, we need to
call the code that unmutes the volume.

The calculated values for the minlen and maxlen fields, which were
rounded to multiples of 2 and clamped to a valid range, were left
unused. Use them in the calculation of the register value rather than
using the raw input minlen and maxlen.
This fixes the following warning with a W=1 build:
drivers/media/rc/img-ir/img-ir-hw.c In function ‘img_ir_free_timing’:
drivers/media/rc/img-ir/img-ir-hw.c +228 :23: warning: variable ‘maxlen’ set but not used [-Wunused-but-set-variable]
