1*c66ec88fSEmmanuel Vadot* EFM32 timer hardware 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotThe efm32 Giant Gecko SoCs come with four 16 bit timers. Two counters can be 4*c66ec88fSEmmanuel Vadotconnected to form a 32 bit counter. Each timer has three Compare/Capture 5*c66ec88fSEmmanuel Vadotchannels and can be used as PWM or Quadrature Decoder. Available clock sources 6*c66ec88fSEmmanuel Vadotare the cpu's HFPERCLK (with a 10-bit prescaler) or an external pin. 7*c66ec88fSEmmanuel Vadot 8*c66ec88fSEmmanuel VadotRequired properties: 9*c66ec88fSEmmanuel Vadot- compatible : Should be "energymicro,efm32-timer" 10*c66ec88fSEmmanuel Vadot- reg : Address and length of the register set 11*c66ec88fSEmmanuel Vadot- clocks : Should contain a reference to the HFPERCLK 12*c66ec88fSEmmanuel Vadot 13*c66ec88fSEmmanuel VadotOptional properties: 14*c66ec88fSEmmanuel Vadot- interrupts : Reference to the timer interrupt 15*c66ec88fSEmmanuel Vadot 16*c66ec88fSEmmanuel VadotExample: 17*c66ec88fSEmmanuel Vadot 18*c66ec88fSEmmanuel Vadottimer@40010c00 { 19*c66ec88fSEmmanuel Vadot compatible = "energymicro,efm32-timer"; 20*c66ec88fSEmmanuel Vadot reg = <0x40010c00 0x400>; 21*c66ec88fSEmmanuel Vadot interrupts = <14>; 22*c66ec88fSEmmanuel Vadot clocks = <&cmu clk_HFPERCLKTIMER3>; 23*c66ec88fSEmmanuel Vadot}; 24
