Subject: [PATCH] serial: sh-sci: suspend/resume wakeup support V2
Date: Thu, 21 Apr 2011 13:08:46 +0000 [thread overview]
Message-ID: <20110421130846.3032.33724.sendpatchset@t400s> (raw)
In-Reply-To: <20110419104344.23764.93511.sendpatchset@t400s>
From: Magnus Damm <damm@opensource.se>
This patch adds wakeup support to the sh-sci driver. The serial
core deals with all details but defaults to wakeup disabled. So
to make use of this feature enable wakeup in sysfs:
echo enabled > /sys/class/tty/ttySC0/power/wakeup
Signed-off-by: Magnus Damm <damm@opensource.se>

Changes since V1:
- drop device_init_wakeup() and enable/disable_irq_wake() bits
- let port->irq point out receive IRQ
