This is based on a search for 'motorcomm,clk-out-frequency-hz = <125000000>' in the kernel. Refer to device tree of other devices with the same properties. After a simple short test, it seems that it is unnecessary. I will delete these two properties in patch v2. > 1800 ps delay basically means that rgmii is not correct type and rgmii-rxid > should be used instead. Indeed, schematic confirms that's the case.
