Date: Tue, 22 Sep 2015 17:00:03 -0700 Message-Id: <1442966406-13198-1-git-send-email-ddaney.cavm@gmail.com> X-Mailer: git-send-email 1.7.11.7 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: David Daney The first patch from Mark Rutland adds the OF device tree binding description, which explains what we are attempting to do here. For MSI messages on GICv3 systems there is some side-band data that accompanies the message, this data is specified in the OF device tree "msi-map" property of the PCI host driver. The second patch adds a parser to get the required information out of the device tree. The third and final patch adds the "msi-map" parsing to gicv3-its. Changes from v1: Factor out the device tree access code to a separate function in drivers/of/irq.c David Daney (2): of/irq: Add new function of_msi_map_rid() irqchip/gicv3-its: Handle OF device tree "msi-map" properties.
