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!
