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.
