You remove the UARTs not used on *Phytec* boards, they could well be
used on other boards. While I agree for the CAN nodes and many others,
UARTs should be kept. Also the GPIOs can be very useful in the MLO. I
suggest that you either change the name of this file to something less
generic (am33xx-phytec-strip.dtsi) or you make a generic more generic
file and remove the unused UARTs / GPIOs in the board specific dts file.
Whatever you do, please keep the am33xx- at the beginning of the
