From 6ba29e916e15c11341b0e043ed643555143e9e64 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Tue, 15 Dec 2015 13:36:38 +0000 Subject: arm64: dts: add .dts for GICv3 Foundation model The ARMv8 Foundation model sports a command line parameter to use a GICv3 emulation instead of the default GICv2 interrupt controller. Add a new .dts file which reuses most of the definitions of the existing model while just adding the required properties for the GICv3 node. This allows the public Foundation model to run with a GICv3.
