TI-NSPIRE timerRequired 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 aclock-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>;};
