    ARM: dts: Enable twl4030 off-idle configuration for selected omaps · 9188883f

    N900 now seems to shut down the external oscillator when hitting
    off-idle.
    
    And Beagle XM seems to have OSC_EN pin connected to allow shutting
    down the oscillator looking at the schematics. The oscillator
    output is cut off in off-idle and you can monitor it from R56 on
    the bottom side of the board near the power jack. Note that for
    beagle we need to also enable the UART wake-up event, the others
    have that enabled in earlier patches.
    
    OMAP37XX EVM (TMDSEVM3730) does not seem to have twl4030 clken
    pin connected, so there is no point trying to enable shutting
    down of the oscillator on it for the extra latency it adds.
