Subject: [PATCH v3 0/3] Add EMAC3 support for sa8540p-ride (devicetree/clk bits)

This is a forward port / upstream refactor of code delivered
downstream by Qualcomm over at [0] to enable the DWMAC5 based
implementation called EMAC3 on the sa8540p-ride dev board.

>From what I can tell with the board schematic in hand,
as well as the code delivered, the main changes needed are:

    1. A new address space layout for /dwmac5/EMAC3 MTL/DMA regs
    2. A new programming sequence required for the EMAC3 base platforms


This series addresses the devicetree and clock changes to support this
hardware bringup.

As requested[1], it has been split up by compile time / maintainer tree.
The associated v3 of the netdev specific changes can be found at [2].
Together, they result in the ethernet controller working for
both controllers on this platform.
