From 853a33ce6932601030f550653aea91a0e0a71511 Mon Sep 17 00:00:00 2001 From: Suravee Suthikulpanit Date: Tue, 25 Nov 2014 18:47:22 +0000 Subject: irqchip: gic-v2m: Add support for ARM GICv2m MSI(-X) doorbell ARM GICv2m specification extends GICv2 to support MSI(-X) with a new register frame. This allows a GICv2 based system to support MSI with minimal changes.
