-* 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";
-	};
