1* Device tree bindings for Atmel Timer Counter Blocks
2- compatible: Should be "atmel,<chip>-tcb", "simple-mfd", "syscon".
3  <chip> can be "at91rm9200" or "at91sam9x5"
4- reg: Should contain registers location and length
5- #address-cells: has to be 1
6- #size-cells: has to be 0
7- interrupts: Should contain all interrupts for the TC block
8  Note that you can specify several interrupt cells if the TC
9  block has one interrupt per channel.
10- clock-names: tuple listing input clock names.
11	Required elements: "t0_clk", "slow_clk"
12	Optional elements: "t1_clk", "t2_clk"
13- clocks: phandles to input clocks.
14
15The TCB can expose multiple subdevices:
16 * a timer
17   - compatible: Should be "atmel,tcb-timer"
18   - reg: Should contain the TCB channels to be used. If the
19     counter width is 16 bits (at91rm9200-tcb), two consecutive
20     channels are needed. Else, only one channel will be used.

22Examples:
23
24One interrupt per TC block:
25	tcb0: timer@fff7c000 {
26		compatible = "atmel,at91rm9200-tcb", "simple-mfd", "syscon";
27		#address-cells = <1>;
28		#size-cells = <0>;
29		reg = <0xfff7c000 0x100>;
30		interrupts = <18 4>;
31		clocks = <&tcb0_clk>, <&clk32k>;
32		clock-names = "t0_clk", "slow_clk";
33
34		timer@0 {
35			compatible = "atmel,tcb-timer";
36			reg = <0>, <1>;
37		};
38
39		timer@2 {
40			compatible = "atmel,tcb-timer";
41			reg = <2>;
42		};
43	};
44
45One interrupt per TC channel in a TC block:
46	tcb1: timer@fffdc000 {
47		compatible = "atmel,at91rm9200-tcb", "simple-mfd", "syscon";
48		#address-cells = <1>;
49		#size-cells = <0>;
50		reg = <0xfffdc000 0x100>;
51		interrupts = <26 4>, <27 4>, <28 4>;
52		clocks = <&tcb1_clk>, <&clk32k>;
53		clock-names = "t0_clk", "slow_clk";
54	};
