 Required properties:
 - compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
 		"intel,pxa27x-gpio", "intel,pxa3xx-gpio",
-		"marvell,pxa93x-gpio", "marvell,mmp-gpio" or
-		"marvell,mmp2-gpio".
+		"marvell,pxa93x-gpio", "marvell,mmp-gpio",
+		"marvell,mmp2-gpio" or marvell,pxa1928-gpio.
 - reg : Address and length of the register set for the device
 - 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-names : Should be the names of irq resources. Each interrupt
+  uses its own interrupt name, so there should be as many interrupt names
+  as referenced interrupts.
 - 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:
+Example for a MMP platform:
 
 	gpio: gpio@d4019000 {
