AM35x Suspend wakeup problem

Other Parts Discussed in Thread: AM3517

Hello,

I'm using AM3517 EVM (SDK 05.02.00.00), i'm able to wakeup from suspend mode sending a character on UART

but I would like to know if it is possible to wakeup using GPIO or touchscreen, even with the new SDK 05.03.02.00 or future release (SDK 5.04.00.00 coming March 30, 2012. )

thanx

Matteo

    I found a solution modifing drivers based on the suggestions found on this page:

    http://elinux.org/OMAP_Power_Management#Known_Problems

    Make sure that driver initialize IRQ with request_irq() and use enable_irq_wake( ) for wake enable. I found that you must disable debounce on the pin.
