Merge branch 'clk-next' of git://git.linaro.org/people/mturquette/linux into next/clock

* 'clk-next' of git://git.linaro.org/people/mturquette/linux:
  clk: Fix CLK_SET_RATE_GATE flag validation in clk_set_rate().
  clk: Provide dummy clk_unregister()
  ARM: Kirkwood: Replace clock gating
  ARM: Orion: Audio: Add clk/clkdev support
  ARM: Orion: PCIE: Add support for clk
  ARM: Orion: XOR: Add support for clk
  ARM: Orion: CESA: Add support for clk
  ARM: Orion: SDIO: Add support for clk.
  ARM: Orion: NAND: Add support for clk, if there is one.
  ARM: Orion: EHCI: Add support for enabling clocks
  ARM: Orion: SATA: Add per channel clk/clkdev support.
  ARM: Orion: UART: Get the clock rate via clk_get_rate().
  ARM: Orion: WDT: Add clk/clkdev support
  ARM: Orion: Eth: Add clk/clkdev support.
  ARM: Orion: SPI: Add clk/clkdev support.
  ARM: Orion: Add clocks using the generic clk infrastructure.
