From 0ca1e290b7c517300bf6cc4f14ebcedb5dfea5cc Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 1 Jul 2011 18:11:22 +0800 Subject: net/fec: gasket needs to be enabled for some i.mx On the recent i.mx (mx25/50/53), there is a gasket inside fec controller which needs to be enabled no matter phy works in MII or RMII mode. The current code enables the gasket only when phy interface is RMII. It's broken when the driver works with a MII phy. The patch uses platform_device_id to distinguish the SoCs that have the gasket and enables it on these SoCs for both MII and RMII mode. Signed-off-by: Shawn Guo Reported-by: Troy Kisky Cc: David S.
