From f833f57ff25450b7161798dceaf8575a48d80249 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 13 Oct 2015 12:51:33 +0100 Subject: irqchip: Convert all alloc/xlate users from of_node to fwnode Since we now have a generic data structure to express an interrupt specifier, convert all hierarchical irqchips that are OF based to use a fwnode_handle as part of their alloc and xlate (which becomes translate) callbacks. As most of these drivers have dependencies (they exchange IRQ specifiers), change them all in a single, massive patch...
