From 638c885185dc2e2b17e59bfe8e9d27b18ed8fade Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Sun, 24 May 2015 16:11:23 +0100 Subject: [PATCH] MIPS: JZ4740: register an irq_domain for the interrupt controller When probing the interrupt controller, register an IRQ domain such that the interrupts can be translated by devicetree code & thus used from devicetree.
