         since the frequency is stored in the irq_freq member of the rtc_device
         structure.  Your driver needs to initialize the irq_freq member during
         init.  Make sure you check the requested frequency is in range of your

+        you cannot actually change the frequency, do not define irq_set_freq.
 
 If all else fails, check out the rtc-test.c driver!
