I checked the gpiod interfaces after original suggestion by Alexandre.

Introducing those mapping tables (much like pinctrl tables) look like
a duplicate effort if Russell will permit adding a DT support. So
I thought that I will reconsider gpiod/pinctrl/etc after fixing
LoCoMo, reiterating IRQ patches, possibly switching to COMMON_CLK
and (finally) thinking about device tree support.
