+title: Freescale MXS GPIO controller

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