Subject: [PATCH 1/2] gpio: implement x86 gpio_to_irq convert function
Date: Tue, 11 Jan 2011 10:55:32 +0000 [thread overview]
Message-ID: <20110111105439.24448.69863.stgit@bob.linux.org.uk> (raw)
From: Alek Du <alek.du@intel.com>
We need this for x86 MID platforms where GPIO interrupts are used. No special
magic is needed so the default 1:1 behaviour will do nicely.
