Subject: [PATCH] m68k: Fall back to __gpio_to_irq() for non-arch GPIOs
Date: Wed, 26 Oct 2011 09:51:55 +0200	[thread overview]
Message-ID: <1319615515-3286-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)

gpiolib provides __gpio_to_irq() to map gpiolib gpios to interrupts - hook
that up on m68k.
