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 devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
