The older SoCs set up the prm wakeup via omap3_prcm_irq_setup. Ideally this would be nowadays done using dts and driver/irqchip though. Maybe see omap3xxx_check_features() and try adding flags for OMAP3_HAS_IO_WAKEUP for am3517? Likely this is the same as for 34xx. It may also have OMAP3_HAS_IO_CHAIN_CTRL like 36xx, but likely not.
