Mark Brown found issue during stm32-dwmac probe: For the past few days networking has been broken on the Avenger 96, a stm32mp157a based platform. The stm32-dwmac driver fails to probe: <6>[ 1.894271] stm32-dwmac 5800a000.ethernet: IRQ eth_wake_irq not found <6>[ 1.899694] stm32-dwmac 5800a000.ethernet: IRQ eth_lpi not found <6>[ 1.905849] stm32-dwmac 5800a000.ethernet: IRQ sfty not found <3>[ 1.912304] stm32-dwmac 5800a000.ethernet: Unable to parse OF data <3>[ 1.918393] stm32-dwmac 5800a000.ethernet: probe with driver stm32-dwmac failed with error -75 which looks a bit odd given the commit contents but I didn't look at the driver code at all.
