119 One-shot mode supported.
121 Timer is per-CPU.
123 Timer may stop in CPU sleep state.
125 Timer supports only 2^n divisors.
131 Timer oscillator's base frequency, if applicable and known.
138 Driver's timer start function pointer.

145 After the event timer functionality is registered, it is controlled via
151 method is called to start the specified event timer.
162 The NULL value there specifies the one-shot mode.

199 When wanted event timer is found,
212 timer functionality is no longer available.
213 On this call, consumer should stop using event timer before the return.
215 After the timer is found and initialized, it can be controlled via
220 Per-CPU event timers can be controlled only from specific CPUs.
223 allows consumer to mark event timer as broken via clearing both one-shot and
228 It releases the event timer for other consumers use.
