Marvell Armada 370 and Armada XP Timers
---------------------------------------
Required properties:
- compatible: Should be either "marvell,armada-370-timer" or
"marvell,armada-xp-timer" as appropriate.
- interrupts: Should contain the list of Global Timer interrupts and
then local timer interrupts
- reg: Should contain location and length for timers register. First
pair for the Global Timer registers, second pair for the
local/private timers.
Clocks required for compatible = "marvell,armada-370-timer":
- clocks : Must contain a single entry describing the clock input
Clocks required for compatible = "marvell,armada-xp-timer":
- clocks : Must contain an entry for each entry in clock-names.
- clock-names : Must include the following entries:
"nbclk" (L2/coherency fabric clock),
"fixed" (Reference 25 MHz fixed-clock).
Examples:
- Armada 370:
timer {
compatible = "marvell,armada-370-timer";
reg = <0x20300 0x30>, <0x21040 0x30>;
interrupts = <37>, <38>, <39>, <40>, <5>, <6>;
clocks = <&coreclk 2>;
};
- Armada XP:
timer {
compatible = "marvell,armada-xp-timer";
reg = <0x20300 0x30>, <0x21040 0x30>;
interrupts = <37>, <38>, <39>, <40>, <5>, <6>;
clocks = <&coreclk 2>, <&refclk>;
clock-names = "nbclk", "fixed";
};
