1* Renesas Multi-Function Timer Pulse Unit 2 (MTU2) 2 3The MTU2 is a multi-purpose, multi-channel timer/counter with configurable 4clock inputs and programmable compare match. 5 6Channels share hardware resources but their counter and compare match value 7are independent. The MTU2 hardware supports five channels indexed from 0 to 4. 8 9Required Properties: 10 11 - compatible: must be one or more of the following: 12 - "renesas,mtu2-r7s72100" for the r7s72100 MTU2 13 - "renesas,mtu2" for any MTU2 14 This is a fallback for the above renesas,mtu2-* entries 15 16 - reg: base address and length of the registers block for the timer module. 17 18 - interrupts: interrupt specifiers for the timer, one for each entry in 19 interrupt-names. 20 - interrupt-names: must contain one entry named "tgi?a" for each enabled 21 channel, where "?" is the channel index expressed as one digit from "0" to 22 "4". 23 24 - clocks: a list of phandle + clock-specifier pairs, one for each entry 25 in clock-names. 26 - clock-names: must contain "fck" for the functional clock. 27 28 29Example: R7S72100 (RZ/A1H) MTU2 node 30 31 mtu2: timer@fcff0000 { 32 compatible = "renesas,mtu2-r7s72100", "renesas,mtu2"; 33 reg = <0xfcff0000 0x400>; 34 interrupts = <0 139 IRQ_TYPE_LEVEL_HIGH>, 35 <0 146 IRQ_TYPE_LEVEL_HIGH>, 36 <0 150 IRQ_TYPE_LEVEL_HIGH>, 37 <0 154 IRQ_TYPE_LEVEL_HIGH>, 38 <0 159 IRQ_TYPE_LEVEL_HIGH>; 39 interrupt-names = "tgi0a", "tgi1a", "tgi2a", "tgi3a", "tgi4a"; 40 clocks = <&mstp3_clks R7S72100_CLK_MTU2>; 41 clock-names = "fck"; 42 }; 43
