/*
* The UART3/4 FIFO and the sidetone memory in McBSP2/3 are
* not correctly reset when the PER powerdomain comes back
* from OFF or OSWR when the CORE powerdomain is kept active.
* See OMAP36xx Erratum i582 "PER Domain reset issue after
* Domain-OFF/OSWR Wakeup". This wakeup dependency is not a
* complete workaround. The kernel must also prevent the PER
* powerdomain from going to OSWR/OFF while the CORE
* powerdomain is not going to OSWR/OFF. And if PER last
* power state was off while CORE last power state was ON, the
* UART3/4 and McBSP2/3 SIDETONE devices need to run a
* self-test using their loopback tests; if that fails, those
* devices are unusable until the PER/CORE can complete a transition
* from ON to OSWR/OFF and then back to ON.
*
* XXX Technically this workaround is only needed if off-mode
* or OSWR is enabled.
