imx8mp EQoS "EQOS_DMA_MODE_SWR stuck"

Greetings,

I'm working on adding board support for an imx8mp SoC board which uses the EQoS MAC interface. I'm finding that eqos_start() fails with 'EQOS_DMA_MODE_SWR stuck'. I believe this is likely a clock issue but not clear what it could be that isn't properly defined in imx8mp.dtsi.

Any ideas?

Best regards,

Tim
