* Optional GPIOX Sub-nodes:

*
* - gpio-dir : GPIO pin direction. Valid only when 'gpio-ctrl'
* is 1.
* 0 = Output
* 1 = Input (Default)
*
* - gpio-lvl : GPIO level. Valid only when 'gpio-ctrl' is 1 and 'gpio-dir' is 0.
*
* 0 = Low (Default)
* 1 = High
*
* - gpio-op-cfg : GPIO output configuration. Valid only when 'gpio-ctrl' is 1
* and 'gpio-dir' is 0.
*
* 0 = CMOS (Default)
* 1 = Open Drain
*
* - gpio-pol : GPIO output polarity select. Valid only when 'gpio-ctrl' is 1
* and 'gpio-dir' is 0.
*
* 0 = Non-inverted, Active High (Default)
* 1 = Inverted, Active Low
*
* - gpio-invert : Defines the polarity of the GPIO pin if configured
* as input.

* 0 = Not inverted (Default)
* 1 = Inverted
*
* - gpio-ctrl : Defines the function of the GPIO pin.
