Okay, got it. before your patch for pinctrl update. I am just totally following
your current style.
For file author name, copyright. i'm really sorry for that. this is
the first time for me
to add a board support, i'm not intended to replace with my name, just too
many files to change, wasn't beware of the difference with author name for new
created file and existing file . will be changed back in the next submit.
