Message-ID: <1413267114-24043-1-git-send-email-peppe.cavallaro@st.com> Date: Tue, 14 Oct 2014 08:11:54 +0200 From: Giuseppe Cavallaro <peppe.cavallaro@...com> To: <netdev@...r.kernel.org> Cc: Giuseppe Cavallaro <peppe.cavallaro@...com> Subject: [PATCH (net.git)] stmmac: platform: fix FIXED_PHY support. On several STi platforms: e.g. stihxxx-b2120 an Ethernet switch is embedded and connected to the stmmac via RGMII mode. So this is managed by using the FIXED_PHY. In that case, the support in the platform needs to be fixed to allow the stmmac to dialog with the switch via fixed-link by using phy_bus_name property.
