From 3c8cf8caa5b217fbb17d0dce7f6bbec1d7da7249 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 22 Aug 2008 17:01:03 +0200 Subject: [PATCH] MIPS: RB532: Use physical addresses for gpio and device controller registers This patch fixes the misuse of virtual addresses for the GPIO and third device controller which would lead to problems while accessing ioremap'd registers.
