media: hantro: postproc: Fix motion vector space allocation
When the post-processor is enabled, the driver allocates
"shadow buffers" which are used for the decoder core,
and exposes the post-processed buffers to userspace.
For this reason, extra motion vector space has to
be allocated on the shadow buffers, which the driver
wasn't doing. Fix it.
This fix should address artifacts on high profile bitstreams.

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.

media: gpu: host1x: mipi: Keep MIPI clock enabled and mutex locked till calibration done
With the split of MIPI calibration into tegra_mipi_calibrate() and
tegra_mipi_wait(), MIPI clock is not kept enabled and mutex is not locked
till the calibration is done.
So, this patch keeps MIPI clock enabled and mutex locked after triggering
start of calibration till its done.
To let calibration process go through its finite sequence codes before
calibration logic waiting for pads idle state added wait time of 75usec
to make sure it sees idle state to apply the results.
This patch renames tegra_mipi_calibrate() as tegra_mipi_start_calibration()
and tegra_mipi_wait() as tegra_mipi_finish_calibration() to be inline
with their usage.
