+* 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: ostm@fcfec000 {
+		compatible = "renesas,r7s72100-ostm", "renesas,ostm";
+		reg = <0xfcfec000 0x30>;
+		interrupts = <GIC_SPI 102 IRQ_TYPE_EDGE_RISING>;
+		clocks = <&mstp5_clks R7S72100_CLK_OSTM0>;
+	};
