Merge tag 'soc-fsl-for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/leo/linux into next/drivers

Pull "FSL/NXP ARM SoC drivers updates for 4.14" from Li Yang:

This adds the DPAA QBMan support for ARM SoCs and a few minor fixes/updates.

This pull request includes updates to the QMAN/BMAN drivers to make
them work on the arm/arm64 architectures in addition to the power
architecture and a few minor update/bug-fix to the soc/fsl drivers.

We got the Reviewed-by from Catalin on the ARM architecture side.

DPAA (Data Path Acceleration Architecture) is a set of hardware
components used on some FSL/NXP QorIQ Networking SoCs, it provides the
infrastructure to support simplified sharing of networking interfaces
and accelerators by multiple CPU cores, and the accelerators
themselves.  The QMan(Queue Manager) and BMan(Buffer Manager) are
infrastructural components within the DPAA framework.  They are used to
manage queues and buffers for various I/O interfaces, hardware
accelerators.
