[libcamera-devel] [PATCH v2 2/2] pipeline: rkisp1: Add support for YUV422

[Paul Elder]

YUV422 is already supported as an output format by the rkisp1 driver.
Add them to the pipeline handler to support them in libcamera as well.

YVU422 is also supported by the driver, but there only exists a
multiplanar V4L2 format, which libcamera is currently unable to map to
from the libcamera YVU422 format. This will be fixed later.

Changes in v2:
- remove YVU422
