    Sorry for a bit late test, but with your patches on Tanix TX6 box I get this
    in dmesg:

    [ 17.431742] sun6i-rtc 7000000.rtc: Failed to set rtc time.
    [ 20.439742] sun6i-rtc 7000000.rtc: rtc is still busy.
    [ 21.435744] sun6i-rtc 7000000.rtc: rtc is still busy.
    [ 24.055741] sun6i-rtc 7000000.rtc: rtc is still busy.
    [ 24.439752] sun6i-rtc 7000000.rtc: rtc is still busy.

    Last line is repeated non-stop.

    Any idea what could be wrong?

    Best regards,
    Jernej
