[PATCH net-next v3 00/12] Add EMAC3 support for sa8540p-ride

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 makes the change for 1 above as well as other housekeeping items
such as converting dt-bindings to yaml, etc.

As requested[1], it has been split up by compile time / maintainer tree.
I will post a link to the associated devicetree changes that together
with this series get the hardware functioning.
