1 * Renesas Multi-Function Timer Pulse Unit 2 (MTU2)
3 The MTU2 is a multi-purpose, multi-channel timer/counter with configurable
4 clock inputs and programmable compare match.
6 Channels share hardware resources but their counter and compare match value
7 are independent. The MTU2 hardware supports five channels indexed from 0 to 4.
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
16 - reg: base address and length of the registers block for the timer module.
18 - interrupts: interrupt specifiers for the timer, one for each entry in
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
24 - clocks: a list of phandle + clock-specifier pairs, one for each entry
26 - clock-names: must contain "fck" for the functional clock.
29 Example: R7S72100 (RZ/A1H) MTU2 node
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>;
