1* Renesas R-Mobile/R-Car Timer Unit (TMU)
2
3The TMU is a 32-bit timer/counter with configurable clock inputs and
4programmable compare match.
5
6Channels share hardware resources but their counter and compare match value
7are independent. The TMU hardware supports up to three channels.
8
9Required Properties:
10
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
17
18  - reg: base address and length of the registers block for the timer module.
19
20  - interrupts: interrupt-specifier for the timer, one per channel.
21
22  - clocks: a list of phandle + clock-specifier pairs, one for each entry
23    in clock-names.
24  - clock-names: must contain "fck" for the functional clock.
25
26Optional Properties:
27
28  - #renesas,channels: number of channels implemented by the timer, must be 2
29    or 3 (if not specified the value defaults to 3).
