    The RTC driver doesn't make much sense without interrupts... look at
    the API in include/linux/rtc.h. Without interrupts, you are just
    querying the RTC status, which (I am guessing) is different on the
    M58T35.

    So, with no interrupts and a different status byte output, it sounds
    like a completely new chrdev driver to me... :)

    BTW, Andrea, since I think (???) this was your patch, why do you disable
    RTC interrupt on Alpha platform? You might as well disable the entire
    driver at that point IMHO...
