Thank you. Andy has already sends me a pull-req for the gpiolib-acpi changes
and I expect Rafael to send me a pull-req (from an immutable branch) for the
ACPI bits soon-ish.

When I merge those both into pdx86 I should be able to pick-up 5/6.

Given the long time this has been in the making I'm tempted to do that
(pick up 5/6 as is) and then we can do further cleanups like looking into
using the existing fixed-regulator code later. My mean reason to do this
would be to get this code into the hands of users starting with the 5.14
kernel.

So question, how usable is this (from the kernel pov, I know userspace
needs work too) once I merge 5/6. Is the kernel-side support for the cameras
on some Surface devices then complete or are more patches necessary in
other subsystems ?

Note another advantage of just merging 5/6 as is and doing the fixed-regulator
bits on top, is that having those in a separate commit makes it easier to
see if these indeed result in a nice cleanup (vs sticking with the current code).

Regards,

Hans
