I think you can simply unconditionally disable clkout. My preferred way of doing what you suggest is probably to register a clock in the CCF. If the clock is not used, it will be automatically disabled. It will also provide a generic way of setting the clkout frequency (some RTC are able to output 32kHZ, 1kHz and 1Hz). -- Alexandre Belloni, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
