From the first glance, the bindings do not follow upstream principles.
You have all the settings (tdm, port config, etc) in the DT, while
they should instead go to the driver. Well, unless you expect that the
board might need to override them.

Hi Dmitry,
The TDM configuration varies per SoC type, since the ethernet port
capabilities of the SoCs vary. So we will have two different TDM
configurations for IPQ5332 and IPQ9574 SoC. The driver also will
need to support future SoC, so we choose to configure this from the
DTSI. The same reason applies to the port scheduler config as well.

Your statements here confirm Dmitry suggestion, so these are not board
specific and should go to the driver. Please read again Dmitry's sentences.

Best regards,
Krzysztof


Sure, we will update the driver to configure the TDM depending on the SoC need.
