Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "The cleanup branch keeps going down in size as we've completed a lot of the major legacy platform removals and conversions. A handful of changes this time around, some of the themes or larger sets are: - A bunch of i.MX cleanups around platform detection, init call cleanups - Misc fixes of missing/implicit includes - Removal of ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (40 commits) ARM: mps2: fix typo ARM: s3c64xx: avoid warning about 'struct device_node' bus: mvebu-mbus: make mvebu_mbus_syscore_ops static bus: mvebu-mbus: fix __iomem on register pointers ARM: tegra: Remove board_init_funcs array ARM: iop: Fix indentation ARM: imx: remove cpu_is_mx*() ARM: imx: remove last call to cpu_is_mx5* ARM: imx: rework mx27_pm_init() call ARM: imx: deconstruct mx3_idle ARM: imx: deconstruct mxc_rnga initialization ARM: imx: remove cpu_is_mx1 check ARM: i.MX: Do not explicitly call l2x0_of_init() ARM: i.MX: system.c: Tweak prefetch settings for performance ARM: i.MX: system.c: Replace magic numbers ARM: i.MX: system.c: Remove redundant errata 752271 code ARM: i.MX: system.c: Convert goto to if statement ARM: Kirkwood: fix kirkwood_pm_init() declaration/type ARM: Kirkwood: make kirkwood_disable_mbus_error_propagation() static ARM: orion5x: make orion5x_legacy_handle_irq static ...
