Merge tag 'imx-soc-3.11' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc
From Shawn Guo: imx soc changes for 3.11: * New SoCs i.MX6 Sololite and Vybrid VF610 support * imx5 and imx6 clock fixes and additions * Update clock driver to use of_clk_init() function * Refactor restart routine mxc_restart() to get it work for DT boot as well * Clean up mxc specific ulpi access ops * imx defconfig updates * tag 'imx-soc-3.11' of git://git.linaro.org/people/shawnguo/linux-2.6: (29 commits) ARM: imx_v6_v7_defconfig: Enable Vybrid VF610 ARM: imx_v6_v7_defconfig: Enable imx-wm8962 by default ARM: clk-imx6qdl: Add clko1 configuration for imx6qdl-sabresd ARM: imx_v6_v7_defconfig: Enable PWM and backlight options ARM: imx: Remove mxc specific ulpi access ops ARM: imx: add initial support for VF610 ARM: imx: add VF610 clock support ARM: imx_v6_v7_defconfig: enable parallel display ARM: imx: clk: No need to initialize phandle struct ARM: imx: irq-common: Include header to avoid sparse warning ARM: imx: Enable mx6 solo-lite support ARM: imx6: use common of_clk_init() call to initialize clocks ARM: imx6q: call of_clk_init() to register fixed rate clocks ARM: imx: imx_v6_v7_defconfig: Select CONFIG_DRM_IMX_TVE ARM: i.MX6: clk: add different DualLite MLB clock config ARM i.MX5: Add S/PDIF clocks ARM i.MX53: Add SATA clock ARM: imx6q: clk: add the eim_slow clock ARM: imx: remove MLB PLL from pllv3 ARM: imx: disable pll8_mlb in mx6q_clks ...
