H A DKconfigdiff a80a0bbee49872c296c9ed9d6af0f510fcd825a7 Wed May 26 23:42:16 CEST 2010 Marc Zyngier <maz@misterjones.org> gpio: add interrupt handling capability to max732x

Most of the GPIO expanders supported by the max732x driver have interrupt
generation capability by reporting changes on input pins through an INT#
pin. This patch implements the irq_chip functionnality (edge detection
only).
