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 changes to support this
hardware bringup.
As requested[1], it has been split up by compile deps / maintainer tree.
The associated v4 of the netdev specific changes can be found at [2],
and is merged.
The clock patch from this series was picked up from v5, leaving just the
devicetree bits here.
Together, they result in the ethernet controller working for
both controllers on this platform.
