[PATCH 0/3] omap5 cpu off mode support

Hi all,

Here are few patches to enable omap5 cpu off mode similar to
what we do for omap4. This seems to save about 0.2W power on
omap5-uevm while idle compared to retention idle.

Note that this won't work for dra7 as it does not support
deeper idle modes.

Regards,

Tony
