From 368400e242dc04963ca5ff0b70654f1470344a0a Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Sat, 10 Dec 2016 21:13:51 +0100 Subject: [PATCH] ARM: dts: vexpress: Support GICC_DIR operations The GICv2 CPU interface registers span across 8K, not 4K as indicated in the DT. Only the GICC_DIR register is located after the initial 4K boundary, leaving a functional system but without support for separately EOI'ing and deactivating interrupts. After this change the system supports split priority drop and interrupt deactivation.
