Either the clock mux logic is glitchless, in which case the RTC is likely to lose at least 31 microseconds per switch; or it's not glitchless, in which case it's unsafe to switch the RTC clock source while the clock isn't gated. Keerthy, before submitting this patch for merging, I'd suggest consulting your hardware folks to figure out which case it is. - Paul -- 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
