This file needs to be accessible from the PRCM core and mach-omap2 board
support code.

- * transition from one low-power state (e.g., CSWR) to another
- * low-power state (e.g., OFF) without first waking up the
- * powerdomain.  This wastes energy.  So OMAP4 chips support the
- * ability to transition a powerdomain power state directly from one
- * low-power state to another.  The function pointed to by
- * @pwrdm_set_lowpwrstchange is intended to configure the OMAP4
- * hardware powerdomain state machine to enable this feature.
