Subject: [PATCH] Input: tca6416-keypad: Suspend/Resume wakeup support
Date: Wed, 16 Mar 2011 14:10:30 +0900 [thread overview]
Message-ID: <20110316051030.2399.19707.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
Extend the tca6416 driver to use enable_irq_wake()
and disable_irq_wake() in the suspend/resume hooks.
This makes it possible to wake up from suspend-to-ram
using a tca6416 key on the sh7372 mackerel board.
