From 52fa212088b141dd05957dc4b7f06a893c8166ad Mon Sep 17 00:00:00 2001 From: Benoit Cousson Date: Wed, 30 Nov 2011 19:21:07 +0100 Subject: ARM: OMAP2/3: intc: Add DT support for TI interrupt controller Add a function to initialize the OMAP2/3 interrupt controller (INTC) using a device tree node. This version take advantage of the new irq_domain_add_legacy API. Replace some printk() with the proper pr_ macro.
