I really like power trees that match the actual schematics, so I'm all
for it ;-) . I don't have a Pinebook Pro myself, so won't be comparing
the power-tree to the schematics myself though.
As for timing, it's too late for 5.6 anyway, so you have time until
around 5.6-rc5 gets released so around 8 weeks.
The other parts you can coordinate between you ;-)
