Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

浏览代码 
Pull ARM SoC platform updates from Arnd Bergmann:
 "Newly added support for additional SoCs:
   - Axis Artpec-6 SoC family
   - Allwinner A83T SoC
   - Mediatek MT7623
   - NXP i.MX6QP SoC
   - ST Microelectronics stm32f469 microcontroller

  New features:
   - SMP support for Mediatek mt2701
   - Big-endian support for NXP i.MX
   - DaVinci now uses the new DMA engine dma_slave_map
   - OMAP now uses the new DMA engine dma_slave_map
   - earlyprintk support for palmchip uart on mach-tango
   - delay timer support for orion

  Other:
   - Exynos PMU driver moved out to drivers/soc/
   - Various smaller updates for Renesas, Xilinx, PXA, AT91, OMAP,
     uniphier"
