* Cirrus Logic CLPS711X Timer Counter
Required properties:
- compatible: Shall contain "cirrus,clps711x-timer".
- reg : Address and length of the register set.
- interrupts: The interrupt number of the timer.
- clocks : phandle of timer reference clock.
Note: Each timer should have an alias correctly numbered in "aliases" node.
Example:
aliases {
timer0 = &timer1;
timer1 = &timer2;
};
timer1: timer@80000300 {
compatible = "cirrus,ep7312-timer", "cirrus,clps711x-timer";
reg = <0x80000300 0x4>;
interrupts = <8>;
clocks = <&clks 5>;
};
timer2: timer@80000340 {
compatible = "cirrus,ep7312-timer", "cirrus,clps711x-timer";
reg = <0x80000340 0x4>;
interrupts = <9>;
clocks = <&clks 6>;
};
