This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIUAwUAVqAGcmCrR//JCVInAQLDog/4x9F0PHGmZhexGfFOpi2Od63Jjx55izRU zRXqRjjFjambOrZuOx8lEGDy/qzqKbsDU8D1P4IUugkDr2bLSXv+NTLZL1kNBIdm YOlJhw/BmzLYqauOHmBzGhtv1FDUk3rqbgTsP5tTWj5LpSkwjmqui3HBZpi+f3Rr YOn+NeQSARiw+51D0b106a9RFshQXRGgn5m3xFjLWhJqshb2z2Ew5cogX/zdwrrM ss1BFomxsvgk6S+snN6v7cEX2iXe3r89qNR5jEW5BgNpQGFsAUeXPr9zzH07L/Qq O7XLw9jt5MX/X5372zVHPb57WoflLbF9cFaaDUZV3eTqt3lC67BTxOtYIdC2i90k E5GYlsy88CRwT2EO+ok/6UTryph+hVv7JqHfbKfnISrbraMCK36DtDTpBIpZ9uYF rRB7ncJZUWBcyoe+qvitSl+2KV54iB1ez2RXsketxM98dDZsfB2M2ImFou1F/Pgg ALvpifPubi/uDe7xNUsSuaT6/3jAomBuNsxnkYJ3NeiH/+duZbOYGkzK/LlcjZyc UrA0IpLfwIFsBNzwfpZPZ1lkEu8Y1YZZ+Hv9k65q1wMuBDgrFI5zUeYrPZi4pN9T Yo1xP9FstVLDouJrpGZo12VIIxR1UBeGqfRI/BZ58LEF3PRq/g2OVFsdQia5gZKr ddiJKSL1Vw== =z1AW -----END PGP SIGNATURE----- Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel.
