There is something wrong with the RTS/CTS pads:

So basically, you are saying that select_input should be set up for CTS
rather than RTS. It seems that the people who generated the macro got
the wrong input from developer.
programming 'select_input' only makes sense for inputs, not outputs.
Since CTS is an output signal, select_input only makes sense for the
RTS function of the pads.
Hi Lothar:
In our imx6 Soc, the CTS is used as a input signal, not as a output signal.
I checked two boards, one is imx6q ARM2 armidillo board, one is
imx6-sabreauto board,
both the boards use the CTS as a input signal.
thanks
