| |
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 time / maintainer tree. The associated v3 of the netdev specific changes can be found at [2]. Together, they result in the ethernet controller working for both controllers on this platform.
