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 (RZ/A1) OSTM
13 - "renesas,r7s9210-ostm" for the R7S9210 (RZ/A2) OSTM
14 - "renesas,ostm" for any OSTM
15 This is a fallback for the above renesas,*-ostm entries
16
17 - reg: base address and length of the register block for a timer channel.
18
19 - interrupts: interrupt specifier for the timer channel.
20
21 - clocks: clock specifier for the timer channel.
22
23Example: R7S72100 (RZ/A1H) OSTM node
24
25 ostm0: timer@fcfec000 {
26 compatible = "renesas,r7s72100-ostm", "renesas,ostm";
27 reg = <0xfcfec000 0x30>;
28 interrupts = <GIC_SPI 102 IRQ_TYPE_EDGE_RISING>;
29 clocks = <&mstp5_clks R7S72100_CLK_OSTM0>;
30 power-domains = <&cpg_clocks>;
31 };
