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 deps / maintainer tree.
The associated v4 of the netdev specific changes can be found at [2].
Together, they result in the ethernet controller working for
both controllers on this platform.
