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. 21 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 }; 55 56 57
