linuxdev,
Nope, not a typo. For that line the input is dtb and the output is dts.
If you would like to add new information to the thread how about a short explanation of why the dtb/dts for the developer kit board did not work for the custom board, given that the custom board is a simple IO subset of the developer’s board.
Even a description of the difference that comes from these two lines would be an improvement:
< vbus-2-supply = <0x9f>;
vbus-2-supply = <0x1a>;
