Hi, Matthias Could you help to fix the misspelling "conolse" with "console" when you merge the patch ? Sean

40-pins connector and uart3 has no pinout, but just has test points (TP47 for TX and TP48 for RX, respectively) nearby uart2. Also, some missing pinctrl is being complemented for those devices.
