1Marvell Armada 370 and Armada XP Timers
2---------------------------------------
3
4Required properties:
5- compatible: Should be either "marvell,armada-370-timer" or
6 "marvell,armada-xp-timer" as appropriate.
7- interrupts: Should contain the list of Global Timer interrupts and
8 then local timer interrupts
9- reg: Should contain location and length for timers register. First
10 pair for the Global Timer registers, second pair for the
11 local/private timers.
12
13Clocks required for compatible = "marvell,armada-370-timer":
14- clocks : Must contain a single entry describing the clock input
15
16Clocks required for compatible = "marvell,armada-xp-timer":
17- clocks : Must contain an entry for each entry in clock-names.
18- clock-names : Must include the following entries:
19 "nbclk" (L2/coherency fabric clock),
20 "fixed" (Reference 25 MHz fixed-clock).

22Examples:

24- Armada 370:
25
26 timer {
27 compatible = "marvell,armada-370-timer";
28 reg = <0x20300 0x30>, <0x21040 0x30>;
29 interrupts = <37>, <38>, <39>, <40>, <5>, <6>;
30 clocks = <&coreclk 2>;
31 };
32
33- Armada XP:
34
35 timer {
36 compatible = "marvell,armada-xp-timer";
37 reg = <0x20300 0x30>, <0x21040 0x30>;
38 interrupts = <37>, <38>, <39>, <40>, <5>, <6>;
39 clocks = <&coreclk 2>, <&refclk>;
40 clock-names = "nbclk", "fixed";
41 };
