Also provide an option to tune RGMII delay value via devicetree. The default delays are retained in the driver. v2 changes: - Added patch to use a common vendor phy id match - Removed dt include header patch because delays should be specied in ps, not register values - Updated DT binding description and commit for optional delay tuning to be clearer on the precedence - Updated dt property name to include vendor instead of phy device name - Switch both VSC8531 and VSC8531-02 to use exact phy id match as they share the same model number - Ensure RCT - Improve optional property read RFC link: https://lore.kernel.org/all/20210629094038.18610-1-harini.katakam@xilinx.com/ Harini Katakam (3): phy: mscc: Use PHY_ID_MATCH_VENDOR to minimize PHY ID table dt-bindings: mscc: Add RGMII RX and TX delay tuning phy: mscc: Add support for VSC8531_02 with RGMII tuning .../bindings/net/mscc-phy-vsc8531.txt | 2 + drivers/net/phy/mscc/mscc.h | 3 ++ drivers/net/phy/mscc/mscc_main.c | 54 +++++++++++++------ 3 files changed, 42 insertions(+), 17 deletions(-)
