We do this by introducing PRCM event > names, which are then matched to the particular PRCM interrupt bit > depending on the specific OMAP SoC being used. > > PRCM interrupts have two priority levels, high or normal. High priority > is needed for IO event handling, so that we can be sure that IO events > are processed before other events.
