From c9fbf7e070bbf9cc7adc1420df87706c62cb04ed Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie@opensource.wolfsonmicro.com> Date: Fri, 26 Mar 2010 16:49:15 +0000 Subject: mfd: Add WM8994 interrupt controller support The WM8994 has an interrupt controller which supports interrupts for both CODEC and GPIO portions of the chip. Support this using genirq, while allowing for systems that do not have an interrupt hooked up. Wrapper functions are provided for the IRQ request and free to simplify the code in consumer drivers when handling cases where IRQs are not set up.
