Subject: [PATCH 3/3] twl4030: enable wakeup on twl4030 IRQ.
Date: Wed, 25 Apr 2012 13:05:24 +1000 [thread overview]
Message-ID: <20120425030524.7832.66013.stgit@notabene.brown> (raw)
In-Reply-To: <20120425025637.7832.14013.stgit@notabene.brown>
Most of the interrupts that come through this line should trigger
wakeups:
power button
RTC alarm
power available
usb plug/unplug
so mark the interrupt as a wakeup interrupt.
This is particularly important for when the interrupt arrives during
the late suspend phase. Without this setting it will be ignored.
