* Renesas OS Timer (OSTM)



The OSTM is a multi-channel 32-bit timer/counter with fixed clock

source that can operate in either interval count down timer or free-running

compare match mode.



Channels are independent from each other.



Required Properties:



  - compatible: must be one or more of the following:

    - "renesas,r7s72100-ostm" for the r7s72100 OSTM

    - "renesas,ostm" for any OSTM

		This is a fallback for the above renesas,*-ostm entries



  - reg: base address and length of the register block for a timer channel.



  - interrupts: interrupt specifier for the timer channel.



  - clocks: clock specifier for the timer channel.



Example: R7S72100 (RZ/A1H) OSTM node



	ostm0: timer@fcfec000 {

		compatible = "renesas,r7s72100-ostm", "renesas,ostm";

		reg = <0xfcfec000 0x30>;

		interrupts = <GIC_SPI 102 IRQ_TYPE_EDGE_RISING>;

		clocks = <&mstp5_clks R7S72100_CLK_OSTM0>;

		power-domains = <&cpg_clocks>;

	};
