From c7eb3f4a1bf59ec10e54bcb74b4ce2150f2b5615 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 8 Oct 2014 15:26:52 +0200 Subject: [PATCH] ARM: realview: move DT GIC to FPGA node This creates a node in the device tree to hold the FPGA devices as a "simple-bus" and moves the GIC found on the FPGA to this node, so it reflects the actual topology of the system.
