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

Pull ARM SoC platform changes from Olof Johansson:
 "This branch contains mostly additions and changes to platform
  enablement and SoC-level drivers.  Since there's sometimes a
  dependency on device-tree changes, there's also a fair amount of
  those in this branch.

  Pieces worth mentioning are:

   - Mbus driver for Marvell platforms, allowing kernel configuration
     and resource allocation of on-chip peripherals.
   - Enablement of the mbus infrastructure from Marvell PCI-e drivers.
   - Preparation of MSI support for Marvell platforms.
   - Addition of new PCI-e host controller driver for Tegra platforms
   - Some churn caused by sharing of macro names between i.MX 6Q and 6DL
     platforms in the device tree sources and header files.
   - Various suspend/PM updates for Tegra, including LP1 support.
   - Versatile Express support for MCPM, part of big little support.
   - Allwinner platform support for A20 and A31 SoCs (dual and quad
     Cortex-A7)
   - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.

  The code that touches other architectures are patches moving MSI
  arch-specific functions over to weak symbols and removal of
  ARCH_SUPPORTS_MSI, acked by PCI maintainers"
