Subject: [PATCH v1 7/8] ARM: dts: Skov i.MX6: start using mainlined kernel dts
Date: Mon, 26 Sep 2022 10:17:39 +0200	[thread overview]
Message-ID: <20220926081740.76968-7-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220926081740.76968-1-o.rempel@pengutronix.de>

Skov i.MX6 device tree is mainline now, so now we can start using it in
the barebox.
