+* Device tree bindings for Atmel Timer Counter Blocks
+- compatible: Should be "atmel,<chip>-tcb", "simple-mfd", "syscon".
+  <chip> can be "at91rm9200" or "at91sam9x5"
+- reg: Should contain registers location and length
+- #address-cells: has to be 1
+- #size-cells: has to be 0
+- 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.
+- clock-names: tuple listing input clock names.
+	Required elements: "t0_clk", "slow_clk"
+	Optional elements: "t1_clk", "t2_clk"
+- clocks: phandles to input clocks.
+
+The TCB can expose multiple subdevices:
+ * a timer
+   - compatible: Should be "atmel,tcb-timer"
+   - reg: Should contain the TCB channels to be used. If the
+     counter width is 16 bits (at91rm9200-tcb), two consecutive
+     channels are needed. Else, only one channel will be used.
+
+Examples:
+
+One interrupt per TC block:
+	tcb0: timer@fff7c000 {
+		compatible = "atmel,at91rm9200-tcb", "simple-mfd", "syscon";
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reg = <0xfff7c000 0x100>;
+		interrupts = <18 4>;
+		clocks = <&tcb0_clk>, <&clk32k>;
+		clock-names = "t0_clk", "slow_clk";
+
+		timer@0 {
+			compatible = "atmel,tcb-timer";
+			reg = <0>, <1>;
+		};
+
+		timer@2 {
+			compatible = "atmel,tcb-timer";
+			reg = <2>;
+		};
+	};
+
+One interrupt per TC channel in a TC block:
+	tcb1: timer@fffdc000 {
+		compatible = "atmel,at91rm9200-tcb", "simple-mfd", "syscon";
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reg = <0xfffdc000 0x100>;
+		interrupts = <26 4>, <27 4>, <28 4>;
+		clocks = <&tcb1_clk>, <&clk32k>;
+		clock-names = "t0_clk", "slow_clk";
+	};
