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-r8a7778" for the r8a7778 TMU
14 - "renesas,tmu-r8a7779" for the r8a7779 TMU
15 - "renesas,tmu" for any TMU.
16 This is a fallback for the above renesas,tmu-* entries
18 - reg: base address and length of the registers block for the timer module.
20 - interrupts: interrupt-specifier for the timer, one per channel.
22 - clocks: a list of phandle + clock-specifier pairs, one for each entry
24 - clock-names: must contain "fck" for the functional clock.
28 - #renesas,channels: number of channels implemented by the timer, must be 2
29 or 3 (if not specified the value defaults to 3).
32 Example: R8A7779 (R-Car H1) TMU0 node
34 tmu0: timer@ffd80000 {
35 compatible = "renesas,tmu-r8a7779", "renesas,tmu";
36 reg = <0xffd80000 0x30>;
37 interrupts = <0 32 IRQ_TYPE_LEVEL_HIGH>,
38 <0 33 IRQ_TYPE_LEVEL_HIGH>,
39 <0 34 IRQ_TYPE_LEVEL_HIGH>;
40 clocks = <&mstp0_clks R8A7779_CLK_TMU0>;
43 #renesas,channels = <3>;
