I prepare this patch to fix dtbs_check when convert fec binding into schema. I realized that we need a "reg" under phy device node, but I also don't know how to add it since the phy is obviously not on board. And I check the phy code, it supports auto scan for PHYs with empty "reg" property.
I looked in the U-Boot code for the nitrogenx6x board: https://source.denx.de/u-boot/u-boot/-/blob/master/board/boundary/nitrogen6x/nitrogen6x.c#L343-356 and it scans for a range of Ethernet PHY addresses. As we can't pass a reg property in the dts in this case, the patch I sent that removes the #address-cells/#size-cells properties looks good, right?
