From: Conor Dooley <conor.dooley@...rochip.com>

Hey Linus,

Rebased as requested, with the dts patch that snuck in dropped.

Cheers,
Conor.

changes in v4:
- rebase on devel
- drop dts patch

changes in v3:
- drop the todos
- rename the kconfig symbol
- move my drivers into a microchip dir
- use power-source instead of custom property

main changes in v2:
- bank voltage is now controllable from dt
- bank lockdown no longer controllable from dt
- dt_node_to_map callback is now a(n attempt at a) new generic function
- some schmitt properties now no longer supported
