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.
+- pad-offset - (required) offset in the IOBASE for the pin to configure
+- gpio-offset - (required) 2 cells
