mfd: PCF50633 gpio support
What the PCF05633 calls as a 'GPIO' is much more than the GPIO in the linux sense and there are only 4 of them - which means, the gpiolib is not used here. Signed-off-by: Balaji Rao <balajirrao@openmoko.org> Cc: Andy Green <andy@openmoko.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
