+* Freescale MPIC timers
+
+Required properties:
+- compatible: "fsl,mpic-global-timer"
+
+- reg : Contains two regions.  The first is the main timer register bank
+  (GTCCRxx, GTBCRxx, GTVPRxx, GTDRxx).  The second is the timer control
+  register (TCRx) for the group.
+
+- fsl,available-ranges: use <start count> style section to define which
+  timer interrupts can be used.  This property is optional; without this,
+  all timers within the group can be used.
+
+- interrupts: one interrupt per timer in the group, in order, starting
+  with timer zero.  If timer-available-ranges is present, only the
+  interrupts that correspond to available timers shall be present.
+
+Example:
+       /* Note that this requires #interrupt-cells to be 4 */
+       timer0: timer@41100 {
+               compatible = "fsl,mpic-global-timer";
+               reg = <0x41100 0x100 0x41300 4>;
+
+               /* Another AMP partition is using timers 0 and 1 */
+               fsl,available-ranges = <2 2>;
+
+               interrupts = <2 0 3 0
+                             3 0 3 0>;
+       };
+
+       timer1: timer@42100 {
+               compatible = "fsl,mpic-global-timer";
+               reg = <0x42100 0x100 0x42300 4>;
+               interrupts = <4 0 3 0
+                             5 0 3 0
+                             6 0 3 0
+                             7 0 3 0>;
+       };
