OK good to hear omap3-beagle.dtb now works for beagles that don't have
the A to B4 hardware timer issue :) And thanks for testing.

It seems the beagle revisions A to B4 are broken for any kind of power
management as the clockevent timer for those boards is not always on.
Probably not worth spending much effort on those. Maybe the PMIC could
be reconfigured on the buggy revisions in addition to the timer quirks
if somebody still cares for those board revisions.

Regards,

Tony
