From cc2fa619a738a052eb90ccbbbc48947a2e2aa1d3 Mon Sep 17 00:00:00 2001 From: Phil Reid Date: Tue, 15 Mar 2016 15:34:33 +0800 Subject: [PATCH] net: stmmac: Don't search for phys if mdio node is defined. If a dt mdio entry has been added least assume that we wont search for phys attached. The DT and of_mdiobus_register already do this. This stops DSA phys being found and phys created for them, as this is handled by the DSA driver. Signed-off-by: Phil Reid Acked-by: Giuseppe Cavallaro Signed-off-by: David S.
