From e4540aa94f9b3e75528d9091524e7d82a0650f10 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 4 Aug 2009 10:52:57 +0000 Subject: [PATCH] cpmac: wait longer after MDIO reset This patch slows down the MDIO_ALIVE busy waiting to let switches and PHY come up after reset. Previous loop was too quick for IC+175C and ADM6996C/L switches to come up. Signed-off-by: Florian Fainelli Signed-off-by: David S.
