From 76e61eaa55e33ea51205fad633393d1ae10311c5 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 4 Aug 2009 10:52:52 +0000 Subject: [PATCH] cpmac: add support for fixed PHY This patch adds support for fixed PHY connected in MII mode to cpmac. We allow external and dumb_switch module parameters to override the PHY detection process since they are always connected with MDIO bus identifier 0. This lets fixed PHYs to be detected correctly and be connected to the their corresponding MDIO bus identifier. Signed-off-by: Florian Fainelli Signed-off-by: David S.
