Hello,

This patch series adds support for the generic line-based metadata
support API. The API is currently under development, with the latest
version v8 posted to the linux-media mailing list in [1].

The series starts with two improvements to media-ctl (1/8) and
v4l2-compliance (2/8). They do not depend on the new API, and can be
merged already. The next 6 patches then implement support for the new
API, and should not be merged until the API is ready to be merged in the
kernel.

This has been tested on a Raspberry Pi 4 with an IMX219 sensor, and the
in-progress work to upstream the Raspberry Pi Unicam driver. The kernel
code can be found in [2], and will be posted shortly to the linux-media
mailing list.
