From mboxrd@z Thu Jan 1 00:00:00 1970 From: clabbe.montjoie@gmail.com (Corentin Labbe) Date: Sat, 26 Aug 2017 09:33:08 +0200 Subject: [PATCH v4 2/5] ARM: dts: sunxi: h3/h5: represent the mdio switch used by sun8i-h3-emac In-Reply-To: <20170826073311.25612-1-clabbe.montjoie@gmail.com> References: <20170826073311.25612-1-clabbe.montjoie@gmail.com> Message-ID: <20170826073311.25612-3-clabbe.montjoie@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Since dwmac-sun8i could use either an integrated PHY or an external PHY (which could be at same MDIO address), we need to represent this selection by a MDIO switch.
