Subject: [PATCH v8 04/10] arm: dts: sunxi: h3/h5: represent the mdio switch used by sun8i-h3-emac
Date: Mon, 23 Oct 2017 20:56:20 +0200	[thread overview]
Message-ID: <20171023185626.31793-5-clabbe.montjoie@gmail.com> (raw)
In-Reply-To: <20171023185626.31793-1-clabbe.montjoie@gmail.com>

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.
