   3 This IP provides 3 types of timer along with PWM functionality:
   4 - advanced-control timers consist of a 16-bit auto-reload counter driven by a programmable
   5   prescaler, break input feature, PWM outputs and complementary PWM ouputs channels.
   6 - general-purpose timers consist of a 16-bit or 32-bit auto-reload counter driven by a
   7   programmable prescaler and PWM outputs.
   8 - basic timers consist of a 16-bit auto-reload counter driven by a programmable prescaler.

  10 Required parameters:
  11 - compatible: must be "st,stm32-timers"
  12
  13 - reg:                  Physical base address and length of the controller's
  14                         registers.
  15 - clock-names:          Set to "int".
  16 - clocks:               Phandle to the clock used by the timer module.
  17                         For Clk properties, please refer to ../clock/clock-bindings.txt
  18
  19 Optional parameters:
  20 - resets:               Phandle to the parent reset controller.
  21                         See ../reset/st,stm32-rcc.txt
  22
  23 Optional subnodes:
  24 - pwm:                  See ../pwm/pwm-stm32.txt
  25 - timer:                See ../iio/timer/stm32-timer-trigger.txt

  27 Example:
  28         timers@40010000 {
  29                 #address-cells = <1>;
  30                 #size-cells = <0>;
  31                 compatible = "st,stm32-timers";
  32                 reg = <0x40010000 0x400>;
  33                 clocks = <&rcc 0 160>;
  34                 clock-names = "int";
  35
  36                 pwm {
  37                         compatible = "st,stm32-pwm";
  38                         pinctrl-0       = <&pwm1_pins>;
  39                         pinctrl-names   = "default";
  40                 };
  41
  42                 timer@0 {
  43                         compatible = "st,stm32-timer-trigger";
  44                         reg = <0>;
  45                 };
  46         };
