Based on chatting with Paul it seems that we most likely don't have
bits for sysc_flags for SYSC_HAS_EMUFREE or SYSS_HAS_RESET_STATUS
either. So applying the updated patch below, and the SSI dts changes
into omap-for-v3.16/dt-v2.

I'm keeping your previous ack Sebastian as the the idlemodes did
not change from the previous version, hopefully that's OK with you.

Regards,

Tony

Subject: [PATCH] ARM: OMAP2+: Fix ssi hwmod entry to allow idling

The current entry prevents system from idling if
the hwmod is defined in the .dts file so let's
change the idlemodes.

Note that we probably don't have SYSC_HAS_EMUFREE
or SYSS_HAS_RESET_STATUS either. If we do, those
can be added later on.
