From 4986b996882d82c68ab54b822d7cfdd7dd35f19a Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 7 Mar 2011 21:59:34 +0000 Subject: [PATCH] net: sh_eth: remove the SH_TSU_ADDR The defination is hardcoded in this driver for some CPUs. This patch modifies to get resource of TSU address from platform_device. Signed-off-by: Yoshihiro Shimoda Signed-off-by: David S.
