From 471036b2b895789c2305428fd879006468e4a758 Mon Sep 17 00:00:00 2001 From: Suravee Suthikulpanit Date: Thu, 10 Dec 2015 08:55:27 -0800 Subject: acpi: pci: Setup MSI domain for ACPI based pci devices This patch introduces pci_msi_register_fwnode_provider() for irqchip to register a callback, to provide a way to determine appropriate MSI domain for a pci device. It also introduces pci_host_bridge_acpi_msi_domain(), which returns the MSI domain of the specified PCI host bridge with DOMAIN_BUS_PCI_MSI bus token. Then, it is assigned to pci device.
