Those autodeps are only there because one of the old CDP trees had them in there. Talking with some people at TI, as I understand it, they are only useful for working around hardware bugs. As far as I know, as long as a target module has its main clock and interface clock enabled, the PRCM should not assert its SIdleReq line to the module, and so the module should never enter idle. But no one seems to have an authoritative idea of which autodeps are still needed, and which are not. Perhaps you, or someone else, might like to try seeing which ones can be safely removed? After applying this patch here: http://marc.info/?l=linux-omap&m=129962861605157&w=2 it should be possible to simply set a CLKDM_NO_AUTODEPS flag on a struct clockdomain, and then no autodep will be added. regards - Paul -- 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
