 Required properties:
 - compatible : Should be "mrvl,pxa-gpio" or "mrvl,mmp-gpio"
 - reg : Address and length of the register set for the device
-- interrupts : Should be the port interrupt shared by all gpio pins, if
-- interrupt-name : Should be the name of irq resource.
-  one number.
+- interrupts : Should be the port interrupt shared by all gpio pins.
+  There're three gpio interrupts in arch-pxa, and they're gpio0,
+  gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
+  gpio_mux.
+- interrupt-name : Should be the name of irq resource. Each interrupt
+  binds its interrupt-name.
+- interrupt-controller : Identifies the node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an
+  interrupt source.
 - gpio-controller : Marks the device node as a gpio controller.
 - #gpio-cells : Should be one.  It is the pin number.
 
 Example:
 
         gpio: gpio@d4019000 {
-                compatible = "mrvl,mmp-gpio", "mrvl,pxa-gpio";
+                compatible = "mrvl,mmp-gpio";
                 reg = <0xd4019000 0x1000>;
-                interrupts = <49>, <17>, <18>;
-                interrupt-name = "gpio_mux", "gpio0", "gpio1";
+                interrupts = <49>;
+                interrupt-name = "gpio_mux";
                 gpio-controller;
                 #gpio-cells = <1>;
                 interrupt-controller;
