+ * - init
+ *   Initialise the kernels jiffy timer source, claim interrupt
+ *   using setup_irq.  This is called early on during initialisation
+ *   while interrupts are still disabled on the local CPU.
+ * - suspend
+ *   Suspend the kernel jiffy timer source, if necessary.  This
+ *   is called with interrupts disabled, after all normal devices
+ *   have been suspended.  If no action is required, set this to
+ *   NULL.
+ * - resume
+ *   Resume the kernel jiffy timer source, if necessary.  This
+ *   is called with interrupts disabled before any normal devices
+ *   are resumed.  If no action is required, set this to NULL.
+ * - offset
+ *   Return the timer offset in microseconds since the last timer
+ *   interrupt.  Note: this must take account of any unprocessed
+ *   timer interrupt which may be pending.
