Fixes: 070246e4674b ("net: stmmac: Fix for mismatched host/device DMA address width") is when support for different DMA address widths was added. This fix cannot easily be back ported past that. 070246e4674b first appears in v6.3-rc4. dwmac-qcom-ethqos.c first appears in v5.1-rc1. However, Qualcomm did not start hacking on it until v6.7-rc6. It is unclear to me without a deep dive when Qualcomm actually started using this driver. We might actually be looking at this the wrong way, and should in fact be looking at when a DT patch was added that made use of the driver, not the driver itself. If it was not used, it cannot be broken.... Andrew
