-* 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";
- };
