From e6dc195c1c69ea525f5001f72d666ac8342139e4 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 14 Feb 2014 10:26:15 +0100 Subject: ARM: integrator: get rid of The Integrator has a custom header defining the BUS_OFFSET for *_to_bus and bus_to_* operations as offset from 0x80000000. This switches the Integrator over to using the mechanism introduced for the Keystone to provide the same offset using the device tree, deletes and augments the Integrator device tree to provide the bus offset.
