1* Freescale MPIC timers
2
3Required properties:
4- compatible: "fsl,mpic-global-timer"
5
6- reg : Contains two regions.  The first is the main timer register bank
7  (GTCCRxx, GTBCRxx, GTVPRxx, GTDRxx).  The second is the timer control
8  register (TCRx) for the group.
9
10- fsl,available-ranges: use <start count> style section to define which
11  timer interrupts can be used.  This property is optional; without this,
12  all timers within the group can be used.
13
14- interrupts: one interrupt per timer in the group, in order, starting
15  with timer zero.  If timer-available-ranges is present, only the
16  interrupts that correspond to available timers shall be present.

18Example:
19	/* Note that this requires #interrupt-cells to be 4 */
20	timer0: timer@41100 {
21		compatible = "fsl,mpic-global-timer";
22		reg = <0x41100 0x100 0x41300 4>;
23
24		/* Another AMP partition is using timers 0 and 1 */
25		fsl,available-ranges = <2 2>;
26
27		interrupts = <2 0 3 0
28		              3 0 3 0>;
29	};
30
31	timer1: timer@42100 {
32		compatible = "fsl,mpic-global-timer";
33		reg = <0x42100 0x100 0x42300 4>;
34		interrupts = <4 0 3 0
35		              5 0 3 0
36		              6 0 3 0
37		              7 0 3 0>;
38	};
