1Atmel AT91 device tree bindings.
2================================
3
4PIT Timer required properties:
5- compatible: Should be "atmel,at91sam9260-pit"
6- reg: Should contain registers location and length
7- interrupts: Should contain interrupt for the PIT which is the IRQ line
8 shared across all System Controller members.
9
10TC/TCLIB Timer required properties:
11- compatible: Should be "atmel,<chip>-pit".
12 <chip> can be "at91rm9200" or "at91sam9x5"
13- reg: Should contain registers location and length
14- interrupts: Should contain all interrupts for the TC block
15 Note that you can specify several interrupt cells if the TC
16 block has one interrupt per channel.
17
18Examples:
19
20One interrupt per TC block:
21 tcb0: timer@fff7c000 {
22 compatible = "atmel,at91rm9200-tcb";
23 reg = <0xfff7c000 0x100>;
24 interrupts = <18 4>;
25 };
26
27One interrupt per TC channel in a TC block:
28 tcb1: timer@fffdc000 {
29 compatible = "atmel,at91rm9200-tcb";
30 reg = <0xfffdc000 0x100>;
31 interrupts = <26 4 27 4 28 4>;
32 };
