1* Renesas OS Timer (OSTM)
2
3The OSTM is a multi-channel 32-bit timer/counter with fixed clock
4source that can operate in either interval count down timer or free-running
5compare match mode.
6
7Channels are independent from each other.
8
9Required Properties:
10
11 - compatible: must be one or more of the following:
12 - "renesas,r7s72100-ostm" for the r7s72100 OSTM
13 - "renesas,ostm" for any OSTM
14 This is a fallback for the above renesas,*-ostm entries
15
16 - reg: base address and length of the register block for a timer channel.
17
18 - interrupts: interrupt specifier for the timer channel.
19
20 - clocks: clock specifier for the timer channel.
21
22Example: R7S72100 (RZ/A1H) OSTM node
23
24 ostm0: timer@fcfec000 {
25 compatible = "renesas,r7s72100-ostm", "renesas,ostm";
26 reg = <0xfcfec000 0x30>;
27 interrupts = <GIC_SPI 102 IRQ_TYPE_EDGE_RISING>;
28 clocks = <&mstp5_clks R7S72100_CLK_OSTM0>;
29 power-domains = <&cpg_clocks>;
30 };
