1 | J-Core Programmable Interval Timer and Clocksource | ||
2 | |||
3 | Required properties: | ||
4 | |||
5 | - compatible: Must be "jcore,pit". | ||
6 | |||
7 | - reg: Memory region(s) for timer/clocksource registers. For SMP, | ||
8 | there should be one region per cpu, indexed by the sequential, | ||
9 | zero-based hardware cpu number. | ||
10 | |||
11 | - interrupts: An interrupt to assign for the timer. The actual pit | ||
12 | core is integrated with the aic and allows the timer interrupt | ||
13 | assignment to be programmed by software, but this property is | ||
14 | required in order to reserve an interrupt number that doesn't | ||
15 | conflict with other devices. | ||
16 | |||
17 | |||
18 | Example: | ||
19 | |||
20 | timer@200 { | ||
21 | compatible = "jcore,pit"; | ||
22 | reg = < 0x200 0x30 0x500 0x30 >; | ||
23 | interrupts = < 0x48 >; | ||
24 | }; | ||
