Mainline does not have a PHY driver for this. So nothing is
controlling the delays in the PHY. So what you have above works by
luck, and is likely to break once there is a PHY driver. So i suggest
you drop the Ethernet nodes for the moment.

There does appear to be a PHY driver here:

https://github.com/CoreELEC/linux-amlogic/blob/5.15.153_202501/drivers/net/phy/maxio.c

but it has a number of things wrong with it. You might want to search
around and see if there are any cleaner versions around, or if anybody
is working on upstreaming a driver for this PHY.
