+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.
