From 433683a66401adb0150792e725cc4f631c94de46 Mon Sep 17 00:00:00 2001 From: Pawel Moll Date: Tue, 16 Oct 2012 15:27:12 +0100 Subject: ARM: vexpress: Remove motherboard dependencies in the DTS files The way the VE motherboard Device Trees were constructed enforced naming and structure of daughterboard files. This patch makes it possible to simply include the motherboard description anywhere in the main Device Tree and retires the "arm,v2m-timer" alias - any of the motherboard SP804 timers will be used instead.
