Subject: [PATCH] ARM: shmobile: Use ->init_late() on Koelsch
Date: Wed, 20 Nov 2013 03:54:34 +0000 [thread overview]
Message-ID: <20131120035434.30035.69827.sendpatchset@w520> (raw)
In-Reply-To: <20131113223406.20634.52693.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Hook in shmobile_init_late() on Koelsch. This enables some PM
related things like CPUIdle and Suspend-to-RAM.
With this patch applied it is possible to use Suspend-to-RAM:
# echo enabled > /sys/class/tty/ttySC6/power/wakeup
# echo mem > /sys/power/state
(wake by sending a character on the serial console)
Signed-off-by: Magnus Damm <damm@opensource.se>
