-Davinci GPIO controller bindings
+Davinci/Keystone GPIO controller bindings
 
 Required Properties:
-- compatible: should be "ti,dm6441-gpio"
+- compatible: should be "ti,dm6441-gpio", "ti,keystone-gpio"
 
 - reg: Physical base address of the controller and the size of memory mapped
        registers.
 
 - gpio-controller : Marks the device node as a gpio controller.
 
+- #gpio-cells : Should be two.
+  - first cell is the pin number
+  - second cell is used to specify optional parameters (unused)
+
 - interrupt-parent: phandle of the parent interrupt controller.
 
 - interrupts: Array of GPIO interrupt number. Only banked or unbanked IRQs are
