From 49dcd070d0718a8b8db344d7b3d5e278362ecd86 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Tue, 6 Sep 2011 21:29:30 +0530 Subject: [PATCH] mfd: Set twl6030 irq_wake infrastructure up TWL6030 devices have an interrupt line which is connected to application processor like OMAP. These devices support multiple features such as MMC card detect, USB cable detect, RTC interrupt, etc. that must wake up the application processor. With this change, TWL6030 client drivers can make use of irq_wake() if the wakeup is desirable on it's irq events.
