 * @priority: should this interrupt be handled before @priority=false IRQs?
 *
 * Describes interrupt bits inside the PRM_IRQ{ENABLE,STATUS}_MPU* registers.
 * On systems with multiple PRM MPU IRQ registers, the bitfields read from
 * the registers are concatenated, so @offset could be > 31 on these systems -
 * see omap_prm_irq_handler() for more details.  I/O ring interrupts should
