There is something wrong with the RTS/CTS pads:
   The RTS pad is assigned with the CTS's value;
   while the CTS pad is assigned with the RTS's value.

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.
