This is good for testing code, but should not be merged because omap4 has the iopad wake-ups available for uarts. So those can be always enabled.

This just need to become: pinctrl-single,pins = < ... 0x104 (WAKEUP_EN | PIN_INPUT_MUX_MODE0) /* uart3_rx_irrx.uart3_rx_irrx */ ... >; interrupts = <GIC_SPI 74 IRQ_TYPE_LEVEL_HIGH>; };
And so on. For am33xx you need to remux things to GPIO for the wake-up events, so you should maybe test on that instead.

Tony
