Subject: [PATCH v2 07/13] net: fec_imx: use of_get_mac_address() to get mac address out of DT
Date: Wed, 5 Aug 2020 12:16:22 +0200 [thread overview]
Message-ID: <20200805101628.4698-8-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20200805101628.4698-1-o.rempel@pengutronix.de>
A mac address can be provided by the DT over nvmem cell. Start to use
of_get_mac_address() since it will be able to read nvmem cell for us.
