This models the SoC-specific hardware difference directly via the compatible string and avoids per-board configuration properties. - Change rx-internal-delay-ps and tx-internal-delay-ps from enum to minimum/maximum to reflect the actual delay range (0-2400 ps) - Add reference to High-Speed Subsystem documentation in eswin,hsp-sp-csr description. The HSP CSR block is described in Chapter 10 ("High-Speed Interface") of the EIC7700X SoC Technical Reference Manual, Part 4 (EIC7700X_SoC_Technical_Reference_Manual_Part4.pdf): https://github.com/eswincomputing/EIC7700X-SoC-Technical-Reference-Manual/releases - Update dwmac-eic7700.c: - Remove handling of eswin,rx-clk-invert and eswin,tx-clk-invert properties. - Select RX clock inversion based on the new "eswin,eic7700-qos-eth-clk-inversion" compatible string, using match data to apply the required configuration for affected MAC instances (eth1). - Link to v1: https://lore.kernel.org/lkml/20260109080601.1262-1-lizhi2@eswincomputing.com/ Zhi Li (2): dt-bindings: ethernet: eswin: add clock sampling control net: stmmac: eic7700: enable clocks before syscon access and correct RX sampling timing .../bindings/net/eswin,eic7700-eth.yaml | 63 ++++++-- .../ethernet/stmicro/stmmac/dwmac-eic7700.c | 152 +++++++++++++----- 2 files changed, 170 insertions(+), 45 deletions(-) -- 2.25.1
