But above can be supported I guess.
Since you are talking about doing menuconfig and rebuilding kernel so what can be done is when one disable CPUIDLE and PM, one can disabled 32K source as well. And then 32K clocksource init should fail and fallback on gptimer clock source. Vaibhav, Can you update your patch to support above. The patch which I did was doing exactly that but was not using hwmod. The problem with your patch is synctimer hwmod lookup on OMAP will never fail if the hwmod entry is supported. So you might better use failure case of omap_init_clocksource_32k() for fall back on gptimer source as I tried in my patch. That should support the usage mentioned by Ming Lie Regards Santosh -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
