From: Ivan Mikhaylov Date: Mon, 26 May 2014 18:34:39 +0000 (+0400) Subject: emac: aggregation of v1-2 PLB errors for IER register X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=09271db6e0f2b282f9bfe0ab6e8b644a93237c5e;p=linux-beck.git emac: aggregation of v1-2 PLB errors for IER register Aggreagation of version 1-2 because of version 1 can hit PLB errors too. If it's not set so we missing events for PLB bits and driver can't process those interrupts. Signed-off-by: Ivan Mikhaylov Signed-off-by: David S.
