From 4672cddff21f6edde857aa4b523bbc1bfc741cf8 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 6 Sep 2012 09:08:47 +0100 Subject: [PATCH] ARM: 7518/1: integrator: convert AMBA devices to device tree This converts the AMBA (PrimeCell) devices on the Integrator/AP and Integrator/CP over to probing from the Device Tree if the kernel is compiled for Device Tree support. We continue to #ifdef out all non-DT code and vice versa on respective boot type to get a clean cut. We need to add a bunch of auxdata (compare to the Versatile) to handle bus names and callbacks alike.
