From f9b4df4a4d7d1124c450f0713a7a1939c7f1a205 Mon Sep 17 00:00:00 2001 From: Bastian Hecht Date: Wed, 17 Apr 2013 12:34:04 +0200 Subject: [PATCH] ARM: shmobile: r8a7740: Add OF support to initialze the GIC We add a variant to initalize the interrupt controller in case we describe the GIC using the Device Tree and not platform data.
