^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) The Freescale MXS GPIO controller is part of MXS PIN controller.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) The GPIOs are organized in port/bank, each port consists of 32 GPIOs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) As the GPIO controller is embedded in the PIN controller and all the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) GPIO ports share the same IO space with PIN controller, the GPIO node
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) will be represented as sub-nodes of MXS pinctrl node.
