7 title: Freescale MXS GPIO controller
10   - Shawn Guo <shawnguo@kernel.org>
13   The Freescale MXS GPIO controller is part of MXS PIN controller.
15   As the GPIO controller is embedded in the PIN controller and all the
16   GPIO ports share the same IO space with PIN controller, the GPIO node
17   will be represented as sub-nodes of MXS pinctrl node.
