Subject: [RFC 00/12] staging: media: max96712: Add support for streams and multiple sensors

Hi,

This series adds more functionality to the existing max96712 staging
driver allowing multiple sensors to be connected through other
compatible serializers. I tried to split the changes in smaller logical
changes to make them easier to review while not altering the existing
VPG functionality but I could squash all of them together if needed.

The series only supports tunneling mode and uses the first MIPI-CSI
port. Support for more functionality can be added later, if needed.

I sent the set as a RFC because it depends on Sakari's pending internal
pads patch which is needed if we want to have an elegant solution for
allowing the user to switch between streaming from sensors or just
video pattern generation.

Also, the set depends on my previous series which was not yet merged:

Thanks,
Laurentiu
