Atmel AT91 device tree bindings.
================================

PIT Timer required properties:
- compatible: Should be "atmel,at91sam9260-pit"
- reg: Should contain registers location and length
- interrupts: Should contain interrupt for the PIT which is the IRQ line
  shared across all System Controller members.

TC/TCLIB Timer required properties:
- compatible: Should be "atmel,<chip>-pit".
  <chip> can be "at91rm9200" or "at91sam9x5"
- reg: Should contain registers location and length
- interrupts: Should contain all interrupts for the TC block
  Note that you can specify several interrupt cells if the TC
  block has one interrupt per channel.

Examples:

One interrupt per TC block:
	tcb0: timer@fff7c000 {
		compatible = "atmel,at91rm9200-tcb";
		reg = <0xfff7c000 0x100>;
		interrupts = <18 4>;
	};

One interrupt per TC channel in a TC block:
	tcb1: timer@fffdc000 {
		compatible = "atmel,at91rm9200-tcb";
		reg = <0xfffdc000 0x100>;
		interrupts = <26 4 27 4 28 4>;
	};
