From 342b7b741d76bc8aadeff844634348bb2a343d19 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Thu, 27 Sep 2012 09:19:34 +0000 Subject: [PATCH] net: ti cpsw ethernet: set IFCTL_A bit in MACCONTROL For RMII/RGMII mode operation in 100Mbps, the CPSW needs to set the IFCTL_A bits in the MACCONTROL register. For all other PHY modes, this bit is unused, so setting it unconditionally shouldn't cause any trouble. Signed-off-by: Daniel Mack Cc: Mugunthan V N Cc: Vaibhav Hiremath Cc: David S.
