[PATCH 15/16] irqdomain: Introduce irq_domain_create_hierarchy
From: Marc Zyngier <hidden>
Date: 2015-10-06 17:37:22
Also in:
linux-acpi, lkml
Subsystem:
irq domains (irq number mapping library), irq subsystem, the rest · Maintainers:
Thomas Gleixner, Linus Torvalds
As we're about to start converting the various MSI layers to use fwnode_handle instead of device_node, add irq_domain_create_hierarchy as a directly equivalent of irq_domain_add_hierarchy (which still exists as a compatibility interface).
