No /dev/gpiochip[n] on RockPro64.
#1
SBC:    Rockpro64 v2.1 4Gb
OS:     ubuntu 18.04 minimal w / Mate' DE     
        Linux rockpro64 4.4.190-1233-rockchip-ayufan-gd3f1be0ed310 #1 SMP 
        Wed Aug 28 08:59:34 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux

I'm working with the libgpiod library and noticed there is no GPIO
character device on the RockPro64. The GPIO character device exists
on the Odroid XU4, N2 & the Pi 3B. Is this unique to the Rockchip
family of ARM processors?

TIA,

Thank you TlLim.
My interest is with the libgoiod [C] library.
Hope all is well with you and yours.
