A series dealing with gpio configuration cleanup from Haojian Zhuang.

* 'armsoc/pxa' of git://github.com/hzhuang1/linux:
  ARM: pxa: move debug uart code
  ARM: pxa: select PXA935 on saar & tavorevb
  ARM: mmp: add more compatible names in gpio driver
  ARM: pxa: move PXA_GPIO_TO_IRQ macro
  ARM: pxa: remove cpu_is_xxx in gpio driver

* Marvell PXA GPIO controller
Required properties:
- compatible : Should be "mrvl,pxa-gpio" or "mrvl,mmp-gpio"
- compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
"intel,pxa27x-gpio", "intel,pxa3xx-gpio",
"marvell,pxa93x-gpio", "marvell,mmp-gpio" or
"marvell,mmp2-gpio".
- reg : Address and length of the register set for the device
- interrupts : Should be the port interrupt shared by all gpio pins.
There're three gpio interrupts in arch-pxa, and they're gpio0,
