    Subject[PATCH v4 2/2] ARM: dts: pxa: fix the rtc controller
    Date
    The RTC controller is fed by an external fixed 32kHz clock. Yet the
    driver wants to acquire this clock, even though it doesn't make any use
    of it, ie. doesn't get the rate to make calculation.

    Therefore, use the exported 32.768kHz clock in the PXA clock tree to
    make the driver happy and working.

    Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

    Since v1: change the dummy clock by the actual 32.768kHz
    Since v3: remove spurious bracket
