From 443c6ae253e96db9a5800a28d7c61131e81c2dee Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Mon, 24 Jun 2013 14:39:52 +0200 Subject: mfd: max8998: Add irq domain support This patch adds irq domain support for max8998 interrupts. To keep both non-DT and DT worlds happy, simple domain is used, which is linear when no explicit IRQ base is specified and legacy, with static mapping, otherwise.
