Merge tag 'imx-soc' of git://git.pengutronix.de/git/imx/linux-2.6 into next/soc
From Sascha Hauer: ARM i.MX SoC updates for next Mostly clock related updates, most notably the conversion of i.MX31 to a DT based lookup. * tag 'imx-soc' of git://git.pengutronix.de/git/imx/linux-2.6: ARM: clk-imx35: Fix build warnings with W=1 ARM: imx27: add a clock gate to activate SPLL clock ARM: mx31: Replace clk_register_clkdev with clock DT lookup ARM: clk-imx31: Add dummy clock ARM: Let CONFIG_MACH_IMX31_DT be built by default Signed-off-by: Olof Johansson <olof@lixom.net>
