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.
