-. STMicroelectronics STM32 timer
-
-The STM32 MCUs family has several general-purpose 16 and 32 bits timers.
-
-Required properties:
-- compatible : Should be "st,stm32-timer"
-- reg : Address and length of the register set
-- clocks : Reference on the timer input clock
-- interrupts : Reference to the timer interrupt
-
-Optional properties:
-- resets: Reference to a reset controller asserting the timer
-
-Example:
-
-timer5: timer@40000c00 {
-	compatible = "st,stm32-timer";
-	reg = <0x40000c00 0x400>;
-	interrupts = <50>;
-	resets = <&rrc 259>;
-	clocks = <&clk_pmtr1>;
-};
