From 5c42e8c4a9c86ea26ed4ecb732a842dea0dfb6b6 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Tue, 15 Dec 2009 16:01:47 -0500 Subject: mfd: Add irq support in 88pm860x 88PM860x is a complex PMIC device. It contains touch, charger, sound, rtc, backlight, led, and so on. Host communicates to 88PM860x by I2C bus. Use thread irq to support this usage case.
