From fdb838cdae4d4f2a478e5cfdd84026f7960b69dd Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Mon, 7 Mar 2011 05:49:47 +0000 Subject: dsa/mv88e6060: support nonzero mii base address The mv88e6060 uses either the lower 16 or upper 16 mii addresses, depending on the value of the EE_CLK/ADDR4 pin. Support both configurations by using the sw_addr setting as base address. Signed-off-by: Peter Korsgaard Acked-by: Lennert Buytenhek Signed-off-by: David S.
