media: staging: rkisp1: uapi: remove __packed

The driver access struct's fields one by one, they are not blindly
copied to/from the hardware, so we can remove __packed from the
structs.

Tested on Scarlet Chromebook with ChromeOS stack and verified images
with the Camera app.

In the irq handler 'rkisp1_params_isr', the lock 'config_lock'
should be held as long as the current buffer is used. Otherwise the
stop_streaming calback might remove it from the list and
pass it to userspace while it is referenced in the irq handler.

media: rcar-vin: Unconditionally unregister notifier on remove

If the VIN device is part of a group of VIN devices (all Gen3 boards)
there is no reason to only unregister the group notifier if the VIN that
registers the notifier is removed. The VIN that registers the notifier
is always the last VIN device to be bound, so keeping the notifier
around after any VIN is unbound creates an unbalanced state where no VIN
in the group is operational.

Fix this by unconditionally unregistering the notifier when any VIN
device is unbound. Unregistering the notifier will lead to unbound()
being called and all video devices exposed by any VIN instance to be
removed.

The lock was only needed to protect the check which VIN registers the
notifier and is no longer needed.

The sole reason for this was so that it would be possible to get a
mmp_camera from a platform_device in suspend/resume/remove hooks, because
drvdata used to be used by the v4l core.

There is no need to queue an empty buffer for signaling a last frame,
because all frames are separate from each other in JPEG.

media: tegra-video: Add CSI MIPI pads calibration

CSI MIPI pads need to be enabled and calibrated for capturing from
the external sensor or transmitter.

MIPI CAL unit calibrates MIPI pads pull-up, pull-down and termination
impedances. Calibration is done by co-work of MIPI BIAS pad and MIPI
CAL control unit.

Triggering calibration start can happen any time after MIPI pads are
enabled but calibration results will be latched and applied to MIPI
pads by MIPI CAL unit only when the link is in LP11 state and then
calibration status register gets updated.

This patch enables CSI MIPI pads and calibrates them during streaming.

Tegra CSI receiver is able to catch the very first clock transition.
So, CSI receiver is always enabled prior to sensor streaming and
trigger of calibration start is done during CSI subdev streaming and
status of calibration is verified after sensor stream on.
