title: Renesas R-Mobile/R-Car Timer Unit (TMU)

maintainers:
  - Geert Uytterhoeven <geert+renesas@glider.be>
  - Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

description:
  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.
