1 * Renesas R-Car Timer Unit (TMU)
3 The TMU is a 32-bit timer/counter with configurable clock inputs and
4 programmable compare match.
6 Channels share hardware resources but their counter and compare match value
7 are independent. The TMU hardware supports up to three channels.
11 - compatible: must contain "renesas,tmu"
13 - reg: base address and length of the registers block for the timer module.
15 - interrupts: interrupt-specifier for the timer, one per channel.
17 - clocks: a list of phandle + clock-specifier pairs, one for each entry
19 - clock-names: must contain "fck" for the functional clock.
23 - #renesas,channels: number of channels implemented by the timer, must be 2
24 or 3 (if not specified the value defaults to 3).
27 Example: R8A7779 (R-Car H1) TMU0 node
29 tmu0: timer@ffd80000 {
30 compatible = "renesas,tmu";
31 reg = <0xffd80000 0x30>;
32 interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>,
33 <0 33 IRQ_TYPE_LEVEL_HIGH>,
34 <0 34 IRQ_TYPE_LEVEL_HIGH>;
35 clocks = <&mstp0_clks R8A7779_CLK_TMU0>;
38 #renesas,channels = <3>;
