Subject: [PATCH net-next 00/11] 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 those adaptations as well as other housekeeping items
such as converting dt-bindings to yaml, adding clock descriptions, etc.

Thanks,
Andrew
