Merge branch 'armsoc/pxa' of git://github.com/hzhuang1/linux into next/boards

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
