Subject: [PATCH 3/3] net: davinci_emac: match the mdio device against its compatible if possible
Date: Tue, 19 Jun 2018 18:09:50 +0200 [thread overview]
Message-ID: <20180619160950.6283-4-brgl@bgdev.pl> (raw)
In-Reply-To: <20180619160950.6283-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Device tree based systems without of_dev_auxdata will have the mdio
device named differently than "davinci_mdio(.0)". In this case use the
device's compatible string for matching.
