These cleanup patches are mainly move stuff around and should all be harmless. They are mainly split out so that other branches can be based on top to avoid conflicts. Notable changes are: * We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no longer used. (Uwe Kleine-König) * The Qualcomm MSM platform is split out into legacy mach-msm and new-style mach-qcom, to allow easier maintainance of the new hardware support without regressions. (Kumar Gala) * A rework of some of the Kconfig logic to simplify multiplatform support (Rob Herring) * Samsung Exynos gets closer to supporting multiplatform (Sachin Kamat and others) * mach-bcm3528 gets merged into mach-bcm (Stephen Warren) * at91 gains some common clock framework support (Alexandre Belloni, Jean-Jacques Hiblot and other French people). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUz/yOWCrR//JCVInAQLOPBAAwTMkMrD8S8ggz6vfiQHZNdRPAC7NUJ46 +eYKmBVi5d6EdnjNuRElWENsh0ZosSAUFHrXsIC2NdH9sAJ9HOqWNNLymuA59Jo9 HZ/Ze6xQXDPNV7TROPoXuIli/2OCOXyyQHJsfI7h9V3PCx31qo0B5OdCxU0mtXK6 r1giREhnJFwfQMF/FTdnzhalFJoSjWwv/nkpNmQDJKRLKj9GzwQqItqw68gV6RzU Gnt6YK+9xC1B0cfWTFhAm6kbr9i7mvHoMG5tE3no2uuJMn4K7TgeMqOyvPWhmUeB EZi656szT1m5VfRWOqG+7coZO2VM4GO4NI0Xfin3GHllugOYls1il/FAfCPMLiwh RvuOmQGCkLIpdkuHop5QaI/h1EzlHA59nzTjmGf1+wWPsm0CIg08XOD9izQbRnN9 EmRqn1/8POIi17xcWyeMp8LB0APsTI+IflZFaYprEY9VlLLA/Pd+7udULhs8Bq8y 1l6fB6aPZKnDKCBy/PEIR+y+EHFEbwfrx6zm/pxVDX6P5DlQMFWL78pdBoJUa2h8 3pm/bSzNU5OSz1nJMLJv2jBTtnM5BvFgQBUi2qJ9Lr+nUhJXKCJ80kE/nOlXoCIU J952p3OhkYTQQcjuUVQeTXvRUOGB7mKok0pDFZNE6c7faqxTCudMABQq/KbMFstU eE3cH5FyYj4= =GcBb -----END PGP SIGNATURE----- Merge tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "These cleanup patches are mainly move stuff around and should all be harmless.
