[1/2] arm64: dts: qcom: sc8280xp: Add ethernet nodes commit: b405d8d500e59e1edc51d934a766ea6127e1e69d [2/2] arm64: dts: qcom: sa8540p-ride: Add ethernet nodes commit: 57827e87be5447559cc3495567349ff002a6b33a Best regards,
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 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], and is merged. The clock patch from this series was picked up from v5, leaving just the devicetree bits here. Together, they result in the ethernet controller working for both controllers on this platform.
