Subject: [PATCH 2/2] common: boards: qemu-virt: use new-style DT overlay syntax
Date: Fri, 17 Feb 2023 18:24:14 +0100	[thread overview]
Message-ID: <20230217172414.1835351-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230217172414.1835351-1-a.fatoum@pengutronix.de>

DTC nowdays also supports a much less verbose syntax for DT overlays
that is internally converted to the usual much more verbose fragment
syntax. Switch to it.

No functional change intended.
