From 7cbb062ade87b987a24aa834bbde32ad8374a4cf Mon Sep 17 00:00:00 2001 From: Shinya Kuribayashi Date: Thu, 17 May 2012 20:11:06 +0900 Subject: USB: gpio_vbus: wakeup support on GPIO VBUS interrupts We'd like to see the system waking up from the system-wide suspend when it gets plugged-in, or the USB cable is pulled out. Also makes it configurable via platform data 'wakeup'.
