Subject: [PATCH 0/5] Driver for Apple ISP and cameras.

Hi.

This series adds support for the camera and ISP system present
on Apple devices using M-series chips. This is a "simple" camera
and does not need any special userspace handling, everything
is handled by the firmware running on an ASC coprocessor.

Patches 1 and 2 add support for special handling neccesary for the
ISP power domains. The rest add the driver itself.
