Hello Scott,
I forgot to mention that I have less error if I use the existing device node
"spi" in the DTS file
# Start of error capture
Got device node from device tree
Got Virtual IRQ
PPC : interrupt hook failed (-22)
# End of capture
So it's able to access the device node and to map "virq" while I had total
failure in using "gpio" I put into DTS
I must make mistake in creating the node "gpio" in the DTS file
I'm using FreeScale Eva board MPC8313ERDB
Thanks,
Duy-Ky

Hi Dave,
I've just tried it and it failed.
Could you elaborate on exactly what you tried? Did you pass the GPIO
device
tree node?
Before I had tried using the function
int virq = of_irq_to_resource(GPIO_IRQ, 0, NULL);
and it failed the same way
The first argument of of_irq_to_resource is a device node pointer, not an
IRQ number. Surely the compiler warned you about this.
