The motivation behind this series is described in commit
("gpio: rcar: Add support for GPIO alternative interrupt").

The reasons for which RFC tag is attached are:
 - Have Renesas/linux-gpio communities been facing GPIO interrupt
   partitioning questions in the past (specifically AP vs RT)?
 - Is it a no-go to have mandatory DTS dependencies like updating
   'interrupts' on specifying the new 'use-alternative-interrupt'?

Many thanks for your comments!
