The way that the "gpio-irq" is specified doesn't look right. If you want to
specify
a gpio line, use the gpio binding. If you just want to specify an interrupt,
use the
"interrupts" property with a proper interrupt-parent.

I'm pretty sure this doesn't even compile. '-' is not part of an identifier in
C.
