To be a bit more precise, I wonder how one is able to use one of those 4
other gpio_chips gpio-davinci registers through an entry with ti,ngpio
set to 144, like it's done in da850.dtsi. With such an entry,
gpio-davinci registers 5 gpio_chips (4 with 32 gpios and one with 16
gpios), but I think currently one is only able to use the first 32 gpios
from within a dt.

Maybe I'm missing some magic somewhere.

I've added two other people to cc from which I think they might be
interested in that topic.
