There is no reason to send OV2680_END_MARGIN extra columns on top of
the mode width and the same for sending extra lines over the mode height.
This sending of extra lines/columns was inherited from the atomisp
ov2680 driver, it is unclear why this was done and this complicates
adding V4L2_CID_VBLANK support, so remove it.

Since commit 63b0cd30b78e ("media: ov2680: Add bus-cfg / endpoint
property verification") the ov2680 driver no longer probes when the
'data-lanes' property is absent.
The OV2680 sensor has only one data lane, so there is no need for
describing it the devicetree.
Remove the unnecessary data-lanes property check.

The sensor gain (both analog and digital) are controlled by a
single gain value where:
- 0dB to 30dB correspond to analog gain
- 30.3dB to 72dB correspond to digital gain
(with 0.3dB step)
Hence, limit the analogue gain value to 100.
For digital gain, support can be added later if needed.

The imx335 reports a recommended pixel area of - 2592x1944.
The driver supported mode however limits it to height=1940.
Fix the height discrepency by correctly the value of height
(with updates to vblank and mode registers).
The IMX335_REG_HTRIMMING should also be corrected to the start
offset(i.e. 48) instead of chosing a abritrary crop start of 384.

When the source device is operating above 1.5 Gbps per lane, it needs to
send the Skew Calibration Sequence before sending any HS data. If the
DPHY is initialized after the source stream is started, then it might
miss the sequence and not be able to receive data properly. Move the
start of source subdev to the end of the sequence to make sure
everything is ready to receive data before the source starts streaming.

First the media device node was created, and if successful it was
marked as 'registered'. This leaves a small race condition where
an application can open the device node and get an error back
because the 'registered' flag was not yet set.
Change the order: first set the 'registered' flag, then actually
register the media device node. If that fails, then clear the flag.

Logitech Rally Bar devices, despite behaving as UVC cameras, have a
different power management system that the other cameras from Logitech.
USB_QUIRK_RESET_RESUME is applied to all the UVC cameras from Logitech
at the usb core. Unfortunately, USB_QUIRK_RESET_RESUME causes undesired
USB disconnects in the Rally Bar that make them completely unusable.
There is an open discussion about if we should fix this in the core or
add a quirk in the UVC driver. In order to enable this hardware, let's
land this patch first, and we can revert it later if there is a
different conclusion.

The Samsung CSIS MIPI receiver provides a start-of-frame interrupt and
a framecount register. As the CSI receiver is the hardware unit that lies
closest to the sensor, the frame counter is the best we can get on these
devices. In case of the ISI available on the i.MX8 M Plus it is also the
only native start-of-frame signal available.
This patch exposes the sof interrupt and the framecount as
V4L2_EVENT_FRAME_SYNC event on the subdevice.
It was tested on a Debix-Som-A with a 6.8-rc4 kernel.

The handled version of request_irq let us remove the free_irq and makes

Let devm handle the life cycle of the irq request.

Instead of handling manually the release of the memory regions let devm
do that for us.

The structure is packed, which requires that all its fields need to be
also packed.
./include/uapi/linux/videodev2.h:1810:2: warning: field within 'struct v4l2_ext_control' is less aligned than 'union v4l2_ext_control::(anonymous at ./include/uapi/linux/videodev2.h:1810:2)' and is usually due to 'struct v4l2_ext_control' being packed, which can lead to unaligned accesses [-Wunaligned-access]
Explicitly set the inner union as packed.
Marking the inner union as 'packed' does not change the layout, since the
whole struct is already packed, it just silences the clang warning. See
also this llvm discussion:

This structure is embedded in multiple other structures that are packed,
which conflicts with it being aligned.

Mark it as being packed.

enable DEBUG_FS if we can to use this driver.

The atomisp driver's Android heritage makes it weird in that
even though it uses MC + subdev-s it is designed to primarily
be controlled through its /dev/video# node.
It implements s_input() on /dev/video# to select which sensor to use,
while ignoring link_setup() calls to enable a link to another sensor.
Add support for selecting the active sensor the MC way by adding
link_setup() support.
The implementation is a bit convoluted due to the atomisp driver's
heritage.

The link from the ISP's source pad to the /dev/video# output v4l2-dev
is always enabled and immutable, mark it as such.
