I could just pull it in, but then I want a clear indication that Greg and
say Andy are happy with this.

The serial patches are missing Gregs explicit ACK and the platform
patch could use Andy's ACK. The last patch adding the
IOT2040 is so obviously out of my GPIO territory that I want
Greg 100% aligned with this.

I am sorry that it is troublesome when things cross subsystem
boundaries, I already stretched it a bit with the things I queued
up because it annoys me too, but this is the process we have :/
