Merge branch 'next/arm64' into next/dt 

Merging in the few patches I had kept separate from main next/dt, since others
got merged here directly.

* next/arm64:
  arm64: defconfig: Enable PCI generic host bridge by default
  arm64: Juno: Add support for the PCIe host bridge on Juno R1
  Documentation: of: Document the bindings used by Juno R1 PCIe host bridge
  arm64: dts: mt8173: Add clocks for SCPSYS unit
  arm64: dts: mt8173: Add subsystem clock controller device nodes
  + Linux 4.3-rc5

<persistent?> is P (Persistent) or N (Not persistent - will not survive

after reboot).

The difference is that for transient snapshots less metadata must be

saved on disk - they can be kept in memory by the kernel.

to allow userspace to advertise its support for seeing "Overflow" in the

snapshot status.  So supported store types are "P", "PO" and "N".

* ARM Juno R1 PCIe interface



This PCIe host controller is based on PLDA XpressRICH3-AXI IP

and thus inherits all the common properties defined in plda,xpressrich3-axi.txt

as well as the base properties defined in host-generic-pci.txt.



Required properties:

 - compatible: "arm,juno-r1-pcie"

 - dma-coherent: The host controller bridges the AXI transactions into PCIe bus

   in a manner that makes the DMA operations to appear coherent to the CPUs.

* PLDA XpressRICH3-AXI host controller



The PLDA XpressRICH3-AXI host controller can be configured in a manner that

makes it compliant with the SBSA[1] standard published by ARM Ltd. For those

scenarios, the host-generic-pci.txt bindings apply with the following additions

to the compatible property:



Required properties:

 - compatible: should contain "plda,xpressrich3-axi" to identify the IP used.
