Merge tag 'imx-soc-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc2
From Shawn Guo: The imx soc changes for 3.10: * Enable anatop, well bisa and RBC for suspend to optimize the power consumption a little bit * Clock changes for TVE, LDB, PATA, SRTC support * Add System Reset Controller (SRC) support for imx5 and imx6 * Add initial imx6dl support based on imx6q code * Kconfig for cpufreq-cpu0, defconfig updates and few other changes * tag 'imx-soc-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6: (275 commits) ARM i.MX53: set CLK_SET_RATE_PARENT flag on the tve_ext_sel clock ARM i.MX53: tve_di clock is not part of the CCM, but of TVE ARM i.MX53: make tve_ext_sel propagate rate change to PLL ARM i.MX53: Remove unused tve_gate clkdev entry ARM i.MX5: Remove tve_sel clock from i.MX53 clock tree ARM: i.MX5: Add PATA and SRTC clocks ARM: imx: do not bring up unavailable cores ARM: imx: add initial imx6dl support ARM: imx1: mm: add call to mxc_device_init ARM: imx_v4_v5_defconfig: Add CONFIG_GPIO_SYSFS ARM: imx_v6_v7_defconfig: Select CONFIG_PERF_EVENTS ARM: i.MX53 Add the cko1, cko2 clock outputs. staging: drm/imx: Use SRC to reset IPU ARM i.MX6q: Add GPU, VPU, IPU, and OpenVG resets to System Reset Controller (SRC) ARM: imx: do not use regmap_read for ANADIG_DIGPROG ARM i.MX6q: set the LDB serial clock parent to the video PLL ARM i.MX6q: Add audio/video PLL post dividers for i.MX6q rev 1.1 ARM i.MX6q: fix ldb di divider and selector clocks ARM i.MX53: fix ldb di divider and selector clocks ARM i.MX: Add imx_clk_divider_flags and imx_clk_mux_flags ... Signed-off-by: Olof Johansson <olof@lixom.net> Trivial change/change conflict in arch/arm/mach-imx/mach-imx6q.c resolved.
