+* Freescale MXS GPIO controller
+
+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.
+
+Required properties for GPIO node:
+- compatible : Should be "fsl,<soc>-gpio".  The supported SoCs include
+  imx23 and imx28.
+- interrupts : Should be the port interrupt shared by all 32 pins.
+- gpio-controller : Marks the device node as a gpio controller.
+- #gpio-cells : Should be two.  The first cell is the pin number and
+  the second cell is used to specify optional parameters (currently
+  unused).
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells : Should be 2.  The first cell is the GPIO number.
+  The second cell bits[3:0] is used to specify trigger type and level flags:
+      1 = low-to-high edge triggered.
+      2 = high-to-low edge triggered.
+      4 = active high level-sensitive.
+      8 = active low level-sensitive.
+
+Note: Each GPIO port should have an alias correctly numbered in "aliases"
+node.
+
+Examples:
+
+aliases {
+	gpio0 = &gpio0;
+	gpio1 = &gpio1;
+	gpio2 = &gpio2;
+	gpio3 = &gpio3;
