3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tony Lindgren <t...@atomide.com>
commit 24b8256a1fb28d357bc6fa09184ba29b4255ba5c upstream.
When booted in legacy mode device_init_wakeup() gets called by
drivers/mfd/twl-core.c when the children are initialized. However, when
booted using device tree, the children are created with
of_platform_populate() instead add_children().
This means that the RTC driver will not have device_init_wakeup() set,
and we need to call it from the driver probe like RTC drivers typically
do.
Without this we cannot test PM wake-up events on omaps for cases where
there may not be any physical wake-up event.
