-* Renesas R-Mobile/R-Car Timer Unit (TMU)
-
-The TMU is a 32-bit timer/counter with configurable clock inputs and
-programmable compare match.
-
-Channels share hardware resources but their counter and compare match value
-are independent. The TMU hardware supports up to three channels.
-
-Required Properties:
-
- - compatible: must contain one or more of the following:
- - "renesas,tmu-r8a7740" for the r8a7740 TMU
- - "renesas,tmu-r8a774a1" for the r8a774A1 TMU
- - "renesas,tmu-r8a774b1" for the r8a774B1 TMU
- - "renesas,tmu-r8a774c0" for the r8a774C0 TMU
- - "renesas,tmu-r8a774e1" for the r8a774E1 TMU
- - "renesas,tmu-r8a7778" for the r8a7778 TMU
- - "renesas,tmu-r8a7779" for the r8a7779 TMU
- - "renesas,tmu-r8a77970" for the r8a77970 TMU
- - "renesas,tmu-r8a77980" for the r8a77980 TMU
- - "renesas,tmu" for any TMU.
- This is a fallback for the above renesas,tmu-* entries
-
- - reg: base address and length of the registers block for the timer module.
-
- - interrupts: interrupt-specifier for the timer, one per channel.
-
- - clocks: a list of phandle + clock-specifier pairs, one for each entry
- in clock-names.
- - clock-names: must contain "fck" for the functional clock.
-
-Optional Properties:
-
- - #renesas,channels: number of channels implemented by the timer, must be 2
- or 3 (if not specified the value defaults to 3).
-
-
-Example: R8A7779 (R-Car H1) TMU0 node
-
- tmu0: timer@...80000 {
- compatible = "renesas,tmu-r8a7779", "renesas,tmu";
- reg = <0xffd80000 0x30>;
- interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>,
- <0 33 IRQ_TYPE_LEVEL_HIGH>,
- <0 34 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp0_clks R8A7779_CLK_TMU0>;
- clock-names = "fck";
-
- #renesas,channels = <3>;
- };
