Merge tag 'mvebu_fixes_for_v3.8' of git://git.infradead.org/users/jcooper/linux into fixes

From Jason Cooper:

fixes for mvebu/kirkwood v3.8
 - use correct uart driver for mvebu boards
 - add a missing DT clocks
 - gpio-poweroff level vs. edge triggering, use gpio_is_valid()
 - remove an inappropriate __init, modules need to access function.
 - various DT fixes
 - error handling in mv_xor

* tag 'mvebu_fixes_for_v3.8' of git://git.infradead.org/users/jcooper/linux:
  pinctrl: mvebu: make pdma clock on dove mandatory
  ARM: Dove: Add pinctrl clock to DT
  dma: mv_xor: fix error handling for clocks
  dma: mv_xor: fix error handling of mv_xor_channel_add()
  arm: mvebu: Add missing ; for cpu node.
  arm: mvebu: Armada XP MV78230 has only three Ethernet interfaces
  arm: mvebu: Armada XP MV78230 has two cores, not one
  clk: mvebu: Remove inappropriate __init tagging
  ARM: Kirkwood: Use fixed-regulator instead of board gpio call
  ARM: Kirkwood: Fix missing sdio clock
  ARM: Kirkwood: Switch TWSI1 of 88f6282 to DT clock providers
  Power: gpio-poweroff: Fix documentation and gpio_is_valid
  ARM: Kirkwood: Fix missing clk for USB device.
  arm: mvebu: Use dw-apb-uart instead of ns16650 as UART driver
