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.
