+Ingenic jz47xx GPIO controller
+
+That the Ingenic GPIO driver node must be a sub-node of the Ingenic pinctrl
+driver node.
+
+Required properties:
+--------------------
+
+ - compatible: Must contain one of:
+    - "ingenic,jz4740-gpio"
+    - "ingenic,jz4770-gpio"
+    - "ingenic,jz4780-gpio"
+ - reg: The GPIO bank number.
+ - interrupt-controller: Marks the device node as an interrupt controller.
+ - interrupts: Interrupt specifier for the controllers interrupt.
+ - #interrupt-cells: Should be 2. Refer to
+   ../interrupt-controller/interrupts.txt for more details.
+ - gpio-controller: Marks the device node as a GPIO controller.
+ - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
+    cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
+    GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
+ - gpio-ranges: Range of pins managed by the GPIO controller. Refer to
+   'gpio.txt' in this directory for more details.
+
+Example:
+--------
+
+&pinctrl {
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	gpa: gpio@0 {
+		compatible = "ingenic,jz4740-gpio";
+		reg = <0>;
+
+		gpio-controller;
+		gpio-ranges = <&pinctrl 0 0 32>;
+		#gpio-cells = <2>;
+
+		interrupt-controller;
+		#interrupt-cells = <2>;
+
+		interrupt-parent = <&intc>;
+		interrupts = <28>;

+Ingenic jz47xx pin controller
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+For the jz47xx SoCs, pin control is tightly bound with GPIO ports. All pins may
+be used as GPIOs, multiplexed device functions are configured within the
+GPIO port configuration registers and it is typical to refer to pins using the
+naming scheme "PxN" where x is a character identifying the GPIO port with
+which the pin is associated and N is an integer from 0 to 31 identifying the
+pin within that GPIO port. For example PA0 is the first pin in GPIO port A, and
+PB31 is the last pin in GPIO port B. The jz4740 contains 4 GPIO ports, PA to
+PD, for a total of 128 pins. The jz4780 contains 6 GPIO ports, PA to PF, for a
+total of 192 pins.
+
+
+Required properties:
+--------------------
+
+ - compatible: One of:
+    - "ingenic,jz4740-pinctrl"
+    - "ingenic,jz4770-pinctrl"
+    - "ingenic,jz4780-pinctrl"
+ - reg: Address range of the pinctrl registers.
+
+
+GPIO sub-nodes
+--------------
+
+The pinctrl node can have optional sub-nodes for the Ingenic GPIO driver;
+please refer to ../gpio/ingenic,gpio.txt.
+
+
+Example:
+--------
+
+pinctrl: pin-controller@10010000 {
+	compatible = "ingenic,jz4740-pinctrl";
+	reg = <0x10010000 0x400>;
