Subject: [PATCH v2] ARM: shmobile: Use ->init_late() on Lager
Date: Wed, 20 Nov 2013 00:02:31 +0000 [thread overview]
Message-ID: <20131120000231.27016.39549.sendpatchset@w520> (raw)
From: Magnus Damm <damm@opensource.se>
Hook in shmobile_init_late() on Lager V2. 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>

Changes since V1:
- added missing include <mach/common.h> to DT reference code
