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.
