Despite\nthis basic ethernet is functional on the Tegra234 platforms that use\nthis driver and as far as I know, we have not tested PTP support with\nthis driver. Hence, the risk of breaking any functionality is low.\n\nThe previous attempt to fix this in the stmmac platform driver, by\nsupporting the Tegra234 PTP clock name, was rejected [0]. The preference\nfrom the netdev maintainers is to fix this in the DT binding for\nTegra234.\n\nThis series fixes this by correcting the device-tree binding to align\nwith the generic name for the PTP clock. I understand that this is\nbreaking the ABI for this device, which we should never do, but this\nis a last resort for getting this fixed. I am open to any better ideas\nto fix this. Please note that we still maintain backward compatibility\nin the driver to allow older device-trees to work, but we don't\nadvertise this via the binding, because I did not see any value in doing\nso.\n\nChanges since V2:\n- Corrected example in dt-binding doc.\n\nChanges since V1:\n- Moved handling of different PTP clock names into Tegra234 MGBE driver.\n- Add changes to update the Tegra234 MGBE DT binding and DT source.\n\n[0] https://lore.kernel.org/linux-tegra/20250612062032.293275-1-jonathanh@nvidia.com/\n\nJon Hunter (3):\n net: stmmac: Fix PTP ref clock for Tegra234\n dt-bindings: net: Fix Tegra234 MGBE PTP clock\n arm64: tegra: Fix Tegra234 MGBE PTP clock\n\n .../bindings/net/nvidia,tegra234-mgbe.yaml | 4 ++--\n arch/arm64/boot/dts/nvidia/tegra234.dtsi | 8 ++++----\n .../net/ethernet/stmicro/stmmac/dwmac-tegra.c | 19 +++++++++++++++++--\n 3 files changed, 23 insertions(+), 8 deletions(-)" }
