title: Blaize BLZP1600 GPIO controller
description:
Blaize BLZP1600 GPIO controller is an implementation of the VeriSilicon
APB GPIO v0.2 IP block. It has 32 ports each of which are intended to be
represented as child nodes with the generic GPIO-controller properties
as described in this binding's file.
