Just want to ping this with my SpacemiT maintainer position, the reset
driver is the last piece that I hope can be accepted during this merge
window (target the v6.20 release), it would help other drivers since it
is a fundamental dependency..

The clock PR which is a dependency for reset has been pulled by Stephen[2],
and the driver also has been tested for a while locally
