[RFC,v2,6/6] media: v4l2-ctrls: add controls for individual zoom lenses
Commit Message
A zoom lens group may consist of several lenses, and in a calibration
context it may be necessary to position the lenses individually. Add a
tuple of V4L2_CID_LENS_CALIB_ZOOMx_{ABSOLUTE,CURRENT,STATUS} controls
for each individual lens, where x = {1...5}.

Wouldn't it be better to have this as an array control? That way the number of
lenses is set by the driver and can be easily read by userspace.

Disclaimer: I do not have enough domain knowledge to comment on if this is the
right solution or not. I can only comment on the control framework specifics.

Are you referring to the _STATUS controls exclusively or is this a
suggestion for _CURRENT and _ABSOLUTE as well?
This would mean that the user space can read out e.g., the status of all
lenses in one batch, right? This would make sense to me.
I am not sure about setting all target positions at the same time ->
I'll have to think about that one a bit.
Best regards,
Michael
