dt-bindings: timer: Convert lsi,zevio-timer to DT schema 



Convert the TI NSPIRE Timer binding to DT schema format. It's a
straight-forward conversion.

TI-NSPIRE timer



Required properties:



- compatible : should be "lsi,zevio-timer".

- reg : The physical base address and size of the timer (always first).

- clocks: phandle to the source clock.



Optional properties:



- interrupts : The interrupt number of the first timer.

- reg : The interrupt acknowledgement registers

	(always after timer base address)



If any of the optional properties are not given, the timer is added as a

clock-source only.



Example:



timer {

	compatible = "lsi,zevio-timer";

	reg = <0x900D0000 0x1000>, <0x900A0020 0x8>;

	interrupts = <19>;

	clocks = <&timer_clk>;

};



Example (no clock-events):



timer {

	compatible = "lsi,zevio-timer";

	reg = <0x900D0000 0x1000>;

	clocks = <&timer_clk>;

};
