1 * Renesas R-Mobile/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 one or more of the following:
12 - "renesas,tmu-r8a7740" for the r8a7740 TMU
13 - "renesas,tmu-r8a774a1" for the r8a774A1 TMU
14 - "renesas,tmu-r8a774b1" for the r8a774B1 TMU
15 - "renesas,tmu-r8a774c0" for the r8a774C0 TMU
16 - "renesas,tmu-r8a7778" for the r8a7778 TMU
17 - "renesas,tmu-r8a7779" for the r8a7779 TMU
18 - "renesas,tmu-r8a77970" for the r8a77970 TMU
19 - "renesas,tmu-r8a77980" for the r8a77980 TMU
20 - "renesas,tmu" for any TMU.
21 This is a fallback for the above renesas,tmu-* entries
23 - reg: base address and length of the registers block for the timer module.
25 - interrupts: interrupt-specifier for the timer, one per channel.
27 - clocks: a list of phandle + clock-specifier pairs, one for each entry
29 - clock-names: must contain "fck" for the functional clock.
33 - #renesas,channels: number of channels implemented by the timer, must be 2
34 or 3 (if not specified the value defaults to 3).
37 Example: R8A7779 (R-Car H1) TMU0 node
39 tmu0: timer@ffd80000 {
40 compatible = "renesas,tmu-r8a7779", "renesas,tmu";
41 reg = <0xffd80000 0x30>;
42 interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>,
43 <0 33 IRQ_TYPE_LEVEL_HIGH>,
44 <0 34 IRQ_TYPE_LEVEL_HIGH>;
45 clocks = <&mstp0_clks R8A7779_CLK_TMU0>;
48 #renesas,channels = <3>;
