Another thing is that we can use a pins-tool program developed by NXP to
 generate the pinctrl configuration code that can be used directly in dts. This
tiny program can avoid pin function conflict. As on i.MX, there are so may pins,
each pin can be used for up 8  function. Configuring the pins is a time-consuming
work.  This tools is very useful for customer to generate the dts code.

I understand, but every silicon vendor has such a tool, all are different,
proprietary and unfriendly to programmers and open source developers, who
need to understand how the hardware is working without magic tools
and secret data sheets to fix bugs.

For the people working with maintaining the code it is paramount that
DTS files are self-descriptive.
