This GPIO is used on the rainier system to indicate the BMC was reset
due to a physical pinhole reset.

This GPIO is used on the everest system to indicate the BMC was reset
due to a physical pinhole reset.
It has been verified that the previous name for this pin has not been
utilized by userspace so the name change is ok.

I couldn't apply these cleanly to any tree I had. I think you had a
patch to add battery-voltage-read-enable, but that's not in the tree
yet.
I fixed them up to apply.
Cheers,
Joel
