   14   The Freescale MXS GPIO controller is part of MXS PIN controller.
   15   The GPIOs are organized in port/bank, each port consists of 32 GPIOs.
   16   As the GPIO controller is embedded in the PIN controller and all the
   17   GPIO ports share the same IO space with PIN controller, the GPIO node
   18   will be represented as sub-nodes of MXS pinctrl node.
