+J-Core Programmable Interval Timer and Clocksource
+
+Required properties:
+
+- compatible: Must be "jcore,pit".
+
+- reg: Memory region(s) for timer/clocksource registers. For SMP,
+ there should be one region per cpu, indexed by the sequential,
+ zero-based hardware cpu number.
+
+- interrupts: An interrupt to assign for the timer. The actual pit
+ core is integrated with the aic and allows the timer interrupt
+ assignment to be programmed by software, but this property is
+ required in order to reserve an interrupt number that doesn't
+ conflict with other devices.
+
+
+Example:
+
+timer@200 {
+ compatible = "jcore,pit";
+ reg = < 0x200 0x30 0x500 0x30 >;
+ interrupts = < 0x48 >;
+};
