Subject: [PATCH v2 2/2] net: davinci_emac: match the mdio device against its compatible if possible
Date: Wed, 20 Jun 2018 10:03:56 +0200 [thread overview]
Message-ID: <20180620080356.11900-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20180620080356.11900-1-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 parent's compatible string for matching
