Hi,
Thank you for your reply.
I forgot to mention thet the question is valid for A20.
The only reference i can find is EINT0 for pin PH00, unfortunately i cant
assign this value in the driver and the only clue i got so far is the use
of gpio_to_irq function
but this doesn't work or i don't know how to use it.
