I've found the problem. My bootloader wasn't initializing the TSC and hence I guess it wasn't working properly, even with Joseph's patch to add a call to the initialization function. So, if I: a) Fix my bootloader to enable TSC. b) Merge Rob's patch series to enable the TSC. This is needed rather than Joseph's patch since the two conflict, and I assume that Rob's patch is going into 3.10. c) Undo my local revert of "ARM: 7674/1: smp: Avoid dummy clockevent being preferred over real hardware clock-event". ... then everything now works. So the only remaining issues are: 1) Should the mux clocks still be defined in the binding document? Prashant didn't seem to think so. 2) I need Mike's ack to apply this series to the Tegra tree. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
