From 3ad909bc8f2ea32fd7d24266c61cd4605feecec8 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 30 Nov 2012 16:30:43 +0100 Subject: [PATCH] ARM: 7588/1: amba: create a resource parent registrator This creates amba_apb_device_add_res() and amba_ahb_device_add_res() respectively, to add devices with another parent than iomem_resource. This is needed to specify that a device is contained in a specific IO range.
