From 7602e05df73f3c775d5ef808c0bc4af9711e4438 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Mon, 2 Jun 2014 19:27:58 +0300 Subject: mfd: ab8500: Fix dt irq mapping The AD8500 defines itself as interrupt-controller in DT, but it doesn't assign DT node to IRQ domain when creates it. As result, of_irq_xx() helpers don't work because they can't find necessary IRQ domain. Hence, fix it by assigning AD8500 core device DT node to IRQ domain when it's created.
