PINE64

Hello all,

I want to bind the FIQ to a GPIO pin input processing.  Is this functionality available on the Pine64? 

I see definition of the pending request in drivers/irqchip/irq-sun4i.c,
#define SUN4I_IRQ_FIQ_PENDING_REG(x)    (0x20 + 0x4 * x)
but no reference or apparent support in the module.

Should I be looking elsewhere?

Thank you,   Joe

Of course its supported ( as it is on any arm device ) but you're going to be hard-pressed to find Allwinner documenting it anywhere.

Hi Joe, try using Duck Duck Go as your search engine. Google gives no return with   SUN4I_IRQ_FIQ   but Duck returns over 30.

I hope this will be of use to you. sq

Marcus, squid4t2 - I appreciate your responses.

squid4t2, thank you for the duckduckgo suggestion. Definitely more to look through.

All the best, Joe
