From b9ae0b50e652b3f6c0df3ab9da7acb7501d3d656 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 26 Jul 2013 10:17:55 -0300 Subject: [PATCH] ARM: mvebu: Initialize MBus using the DT binding Now that the mbus device tree binding has been introduced, we can switch over to it. Also, and since the initialization of the mbus driver is quite fundamental for the system to work properly, this patch adds a BUG() in case mbus fails to initialize.
