1 STM32 Timers driver bindings 2 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. 9 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 26 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 };
