The following patch should fix the tests above for 3530es3beagle.
Care to test and ack as I don't have one?

3530es3beagle retention dynamic idle tests hang on next-20140729.  (Maybe 
other boards fail too - haven't tested any others).  

I just checked that today's linux next works for off-idle and
wake-up events for at least 37xx evm.

I ran the full set of tests across all boards.  The only board that passed 
the dynamic idle testing on next-20140729 was the 3730beaglexm.

37xxevm hangs on the first suspend entry:

If I find some extra time, I'll set up a bisection run.

OK that sounds like some driver suspend regression that needs
to be tracked down. I'm seeing it on my 37xx evm also with
linux next too.

It's commit a71e3c37960ce5f9c6a519bc1215e3ba9fa83e75:

    net: phy: Set the driver when registering an MDIO bus device
    
    mdiobus_register() registers a device which is already bound to a driver.
    Hence, the driver pointer should be set properly in order to track down
    the driver associated to the MDIO bus.
    
    This will be used to allow ethernet driver to pin down a MDIO bus driver,
    preventing it from being unloaded while the PHY device is running.

What's bad is that this went in late during v3.16-rc fixes.  So now v3.16 
itself is broken, and there's no way to fix it.

we have stable releases for that.
