* EFM32 timer hardware
|
|
|
|
The efm32 Giant Gecko SoCs come with four 16 bit timers. Two counters can be
|
|
connected to form a 32 bit counter. Each timer has three Compare/Capture
|
|
channels and can be used as PWM or Quadrature Decoder. Available clock sources
|
|
are the cpu's HFPERCLK (with a 10-bit prescaler) or an external pin.
|
|
|
|
Required properties:
|
|
- compatible : Should be efm32,timer
|
|
- reg : Address and length of the register set
|
|
- clocks : Should contain a reference to the HFPERCLK
|
|
|
|
Optional properties:
|
|
- interrupts : Reference to the timer interrupt
|
|
|
|
Example:
|
|
|
|
timer@40010c00 {
|
|
compatible = "efm32,timer";
|
|
reg = <0x40010c00 0x400>;
|
|
interrupts = <14>;
|
|
clocks = <&cmu clk_HFPERCLKTIMER3>;
|
|
};
