Subject: [PATCH v2 05/10] arm: dts: imx8mp-skov: Add barebox state backend in DTS
Date: Mon,  2 Oct 2023 12:16:49 +0200	[thread overview]
Message-ID: <20231002101654.2373000-6-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20231002101654.2373000-1-o.rempel@pengutronix.de>

Introduce 'state' node to manage device states using barebox state framework.
Set backend to usdhc3 and define storage parameters.

For now, reuse existing layout from Skov i.MX6 variants.
