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