These are updates for platform specific code on 32-bit ARM machines, essentially anything that can not (yet) be expressed using DT files. Noteworthy changes include: - Added support for the TI DRA71x family of SoCs in mach-omap2, this is an new variant of the the DRA72x/DRA74x automotive infotainment chips we already supported for a while. - Added support for the ST STM32F746 SoC, the first Cortex-M7 based microcontroller we support, related to the smaller STM32F4 family. - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see http://elinux.org/RZ-G - SMP is now supported on the OX820 platform - A lot of code in mach-omap2 gets removed as a follow-up to removing support for board files in the previous release - Davinci has some new work to improve USB support - For i.MX, the performance monitor now supports profiling the memory controller using 'perf' Conflicts: arch/arm/mach-shmobile/setup-rcar-gen2.c: rcar_gen2_clocks_init() is gone, calling of_clk_init(NULL) is sufficient now. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAWFMS9WCrR//JCVInAQIG+Q/7BElvubqO/Cc/VEAyoB5iF9OB9wPD2t5p O0KwtrTtzqJZJNGTmPiesR4DMZH07O1XoW8HqvBPeXtB7/t0tmOegwK+WABbpkSE ZQgUjtrIGwteJXYqU2BbhooO8G6mEsfWaqdGX8ZiIk40fPhMN6536lG+JA8DV7uv ckAPHCZkIf34lDtwljN97Cvj1TT9lBFp04bx7alKqfg1IMV+iMSxvSRHuuFlxRCk kzwVXDmFlZLmueU2KbQXTuOUrvehIGlZ/X5QWlxfrjwCwnOvr54p8WDoVWu2UkHm Dc8BVfsBny8mCZJRzfDD1S0PD0mWn1msdOhRb4VRzsC9DnRI4qbL0/Hstu8A7yUQ kBtMyVtFTzvRSclABbHHN6Mnm37AyNwSIKIB8h2U1m7YHqZGwHLaflVT5sf3tl7m 4arTVqHtR8oSU5G5a2FTznMM2rfIx4LcCBbLQxWqzmO4Qrh4j6t7c2i7+VTfFAja 0bToLgTArKK/cep6PWeBnMH14nzlXoKtBf2T8qwQPuAmLKy9E0ZduLKZ01B/nqrj OXcsnG0OUuqU4RgbIaDssRU4ohKIk8JcAl60TdRFhzj+/LTbeMaWVwbWuQS+iHd3 zfzGUoUIhElx0vHt6ghR0BYQadszb1z9V0NEs3UM0v5cWlNodX//3okH8lZmSW6w +fO4dSnIKIA= =BF6Y -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "These are updates for platform specific code on 32-bit ARM machines, essentially anything that can not (yet) be expressed using DT files.
