From a9bb5a4bf9f84256499c802fd397d56d55227e4f Mon Sep 17 00:00:00 2001

Subject: PCMCIA: pxa: convert PXA socket drivers to use new irq/gpio
 management

Convert all the PXA platform socket drivers to use the new irq/gpio
management provided by soc_common.  This relieves these drivers from
having to do anything with these GPIOs other than provide the numbers
to soc_common.
