 Pin nodes must be children of the pinctrl master node and can
 contain the following properties:
-- pad-offset        - (required) offset in the IOBASE for the pin to configured.
-- gpio-offset       - (required) offset in the GPIOBASE for the pin to configured and
-                                       also the bit shift in this register.
-- mode-gpio                    - (optional) standalone property to force the pin into GPIO mode.
-- mode-func                    - (optional) function number to assign to the pin. if 'mode-gpio'
-                                       is set, this property will be ignored.

-- pull-assign       - (optional) this set the pull assignement (up/down) of the pin.
