I don't know how good these are, but that's what we have currently as
most prominent use of gpio-regmap

1) (ongoing) https://lore.kernel.org/linux-gpio/20230606092107.764621-6-jiawenwu@xxxxxxxxxxxxxx/
2) (in the repo)
https://elixir.bootlin.com/linux/v6.4-rc4/source/drivers/gpio/gpio-i8255.c
3) (in the repo)
https://elixir.bootlin.com/linux/v6.4-rc4/source/drivers/gpio/gpio-104-idi-48.c

2) & 3) were converted, so you may see by executing respective `git
log -p -- drivers/gpio/...`.
