* Renesas Multi-Function Timer Pulse Unit 2 (MTU2)
|
|
|
|
The MTU2 is a multi-purpose, multi-channel timer/counter with configurable
|
|
clock inputs and programmable compare match.
|
|
|
|
Channels share hardware resources but their counter and compare match value
|
|
are independent. The MTU2 hardware supports five channels indexed from 0 to 4.
|
|
|
|
Required Properties:
|
|
|
|
- compatible: must be one or more of the following:
|
|
- "renesas,mtu2-r7s72100" for the r7s72100 MTU2
|
|
- "renesas,mtu2" for any MTU2
|
|
This is a fallback for the above renesas,mtu2-* entries
|
|
|
|
- reg: base address and length of the registers block for the timer module.
|
|
|
|
- interrupts: interrupt specifiers for the timer, one for each entry in
|
|
interrupt-names.
|
|
- interrupt-names: must contain one entry named "tgi?a" for each enabled
|
|
channel, where "?" is the channel index expressed as one digit from "0" to
|
|
"4".
|
|
|
|
- clocks: a list of phandle + clock-specifier pairs, one for each entry
|
|
in clock-names.
|
|
- clock-names: must contain "fck" for the functional clock.
|
|
|
|
|
|
Example: R7S72100 (RZ/A1H) MTU2 node
|
|
|
|
mtu2: timer@fcff0000 {
|
|
compatible = "renesas,mtu2-r7s72100", "renesas,mtu2";
|
|
reg = <0xfcff0000 0x400>;
|
|
interrupts = <0 139 IRQ_TYPE_LEVEL_HIGH>,
|
|
<0 146 IRQ_TYPE_LEVEL_HIGH>,
|
|
<0 150 IRQ_TYPE_LEVEL_HIGH>,
|
|
<0 154 IRQ_TYPE_LEVEL_HIGH>,
|
|
<0 159 IRQ_TYPE_LEVEL_HIGH>;
|
|
interrupt-names = "tgi0a", "tgi1a", "tgi2a", "tgi3a", "tgi4a";
|
|
clocks = <&mstp3_clks R7S72100_CLK_MTU2>;
|
|
clock-names = "fck";
|
|
};
