    avr32: Generic clockevents support · e723ff66
    David Brownell authored
    This combines three patches from David Brownell:
      * avr32: tclib support
      * avr32: simplify clocksources
      * avr32: Turn count/compare into a oneshot clockevent device
    
    Register both TC blocks (instead of just the first one) so that
    the AT32/AT91 tclib code will pick them up (instead of just the
    avr32-only PIT-style clocksource).
    
    Rename the first one and its resources appropriately.
    
    More cleanups to the cycle counter clocksource code
    
     - Disable all the weak symbol magic; remove the AVR32-only TCB-based
       clocksource code (source and header).
    
     - Mark the __init code properly.
    
     - Don't forget to report IRQF_TIMER.
    
     - Make the system work properly with this clocksource, by preventing
       use of the CPU "idle" sleep state in the idle loop when it's used.
    
    Package the avr32 count/compare timekeeping support as a oneshot
    clockevent device, so it supports NO_HZ and high res timers.
    This means it also supports plugging in other clockevent devices
    and clocksources.
