How to get camera embedded metadata

[ekeechg]

Hi,nvidia team:
We are adapting a new GMSL camera to Thor. I want get embedded metadata from camera.
beside change “embedded_metadata_height” in device tree, what should I do in driver level?
Is there any sample code or guide? I can hardly find any relevant documents.

I find some user space code to get metadata, but didn’t find “V4L2_CID_ARGUS_METADATA” related code in kernel.

I’m a little confused about how is it transfer to user space and where retrieve it.
