    rtc: ds1307: fix kernel splat due to wakeup irq handling · 51c4cfef
    Felipe Balbi 提交于
    Since commit 3fffd128 ("i2c: allow specifying
    separate wakeup interrupt in device tree") we have
    automatic wakeup irq support for i2c devices. That
    commit missed the fact that rtc-1307 had its own
    wakeup irq handling and ended up introducing a
    kernel splat for at least Beagle x15 boards.
    
    Fix that by reverting original commit _and_ passing
    correct interrupt names on DTS so i2c-core can
    choose correct IRQ as wakeup.
    
    Now that we have automatic wakeirq support, we can
    revert the original commit which did it manually.
    
    Fixes the following warning:

    [   10.359244] rtc-ds1307 2-006f: wake irq already initialized
