Hello, Here I want to introduce a new patch series, which aims to support GMAC functions on S32 SoCs, such as S32G2. This series is originally from NXP's implementation on CodeAurora[1] and it will be required by upstream kernel to configure platform settings at the DWMAC glue layer before activating the DWMAC core on different S32G boards. In this patchset I also introduce more register fields needed by S32 SoCs, such as higher CSR clock ranges and cache coherency settings. For more information please see NXP's GMACSUBSYS Reference Manual[2]. Currently, the whole architecture relies on FDTs offered by ATF[3] on CodeAurora to keep the flexibility of handling multiple S32 platforms since now S32 clks can be triggered via the ARM SCMI clock protocol and clk IDs/ settings can vary according to different board designs. To ensure that the driver can work properly, the dt-binding schemas in this patchset is still required as a reference.
