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. 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'" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (95 commits) ARM: davinci: da830-evm: use gpio descriptor for mmc pins ARM: davinci: da850-evm: use gpio descriptor for mmc pins ARM: davinci: hawk: use gpio descriptor for mmc pins ARM: ARTPEC-6: add select MFD_SYSCON to MACH_ARTPEC6 ARM: davinci: da8xx: Fix ohci device name ARM: oxnas: Add OX820 config and makefile entry ARM: oxnas: Add OX820 SMP support ARM: davinci: PM: fix build when da850 not compiled in ARM: orion5x: remove legacy support of ls-chl ARM: integrator: drop EBI access use syscon ARM: BCM5301X: Add back handler ignoring external imprecise aborts ARM: davinci: PM: support da8xx DT platforms ARM: davinci: PM: cleanup: remove references to pdata ARM: davinci: PM: rework init, remove platform device ARM: Kconfig: Introduce MACH_STM32F746 flag ARM: mach-stm32: Add a new SOC - STM32F746 ARM: shmobile: document SK-RZG1E board ARM: shmobile: r8a7745: basic SoC support ARM: imx: mach-imx6ul: add imx6ull support ARM: zynq: Reserve correct amount of non-DMA RAM ...
