Subject: [PATCH v3 0/6] Microchip mpfs/pic64gx pinctrl part 2

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

Hey Linus,

v3 here, with the rfc dropped. I've still got the property checking
stuff in my todo-list but not tested it sufficiently after the changes
to add generic string properties yet.
I only moved my drivers into the microchip dir, I'll come along and do a
pass on the rest if you're happy with what's here.

Cheers,
Conor.

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
