[PATCH 2/2] ARM: dts: aspeed: zaius: Add gpio line names

From: Andrew Geissler
Date: Fri Mar 06 2020 - 12:02:49 EST


Name the GPIOs to help userspace work with them. The names describe the
functionality the lines provide, not the net or ball name. This makes it
easier to share userspace code across different systems and makes the
use of the lines more obvious.
