From 34b134aebda89888b6985b7a3139e9cbdf209236 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sun, 3 Feb 2013 09:59:45 +0000 Subject: MIPS: pci-ar724x: remove static PCI IO/MEM resources Static resources become impractical when multiple PCI controllers are present. Move the resources into the platform device registration code and change the probe routine to get those from there platform device's resources.
