Merge branch 'pcmcia' of git://git.linaro.org/people/rmk/linux-arm

Pull #3 ARM updates from Russell King:
 "This adds gpio support to soc_common, allowing an amount of code to be
  deleted from each PCMCIA socket driver for the PXA/SA11x0 SoCs."

* 'pcmcia' of git://git.linaro.org/people/rmk/linux-arm:
  PCMCIA: sa1111: rename sa1111 socket drivers to have sa1111_ prefix.
  PCMCIA: make lubbock socket driver part of sa1111_cs
  PCMCIA: add Kconfig control for building sa11xx_base.c
  PCMCIA: sa1111: jornada720: no need to disable IRQs around sa1111_set_io
  PCMCIA: sa1111: pass along sa1111_pcmcia_configure_socket() failure code
  PCMCIA: soc_common: remove explicit wrprot initialization in socket drivers
  PCMCIA: soc_common: remove soc_pcmcia_*_irqs functions
  PCMCIA: sa11x0: h3600: convert to use new irq/gpio management
  PCMCIA: sa11x0: simpad: convert to use new irq/gpio management
  PCMCIA: sa11x0: shannon: convert to use new irq/gpio management
  PCMCIA: sa11x0: nanoengine: convert reset handling to use GPIO subsystem
  PCMCIA: sa11x0: nanoengine: convert to use new irq/gpio management
  PCMCIA: sa11x0: cerf: convert reset handling to use GPIO subsystem
  PCMCIA: sa11x0: cerf: convert to use new irq/gpio management
  PCMCIA: sa11x0: assabet: convert to use new irq/gpio management
  PCMCIA: sa1111: use new per-socket irq/gpio infrastructure
  PCMCIA: pxa: convert PXA socket drivers to use new irq/gpio management
  PCMCIA: soc_common: add GPIO support for card status signals
  PCMCIA: soc_common: move common initialization into soc_common
