+<p class="Pp">This driver uses RTC hardware to supply kernel with time-of-day
+    clock with 1 second resolution and one event timer. This hardware uses base
+    frequency of 32768Hz for advancing time-of-day clock and generating periodic
+    interrupts. Interrupts could be generated with fixed number of frequencies,
+    from 2Hz to 8192Hz, obtained by dividing base frequency by one of supported
+    power-of-2 divisors.</p>
+<p class="Pp">Event timer provided by the driver is irrelevant to CPU power
+    states.</p>
