The J722S CPSW3G is mostly identical to the AM64's, but additionally supports SGMII.

Ah, I just realized that I sent the wrong version of this patch, AM64_CPSW_QUIRK_CUT_THRU only exists in the TI vendor kernel... sorry about this, will fix in v2. Can someone from TI answer if AM64_CPSW_QUIRK_DMA_RX_TDOWN_IRQ is needed for the J722S? Best, Nora
