Can you revert or drop the last two DTS patches? I think I will try a different route to get the split of the tpcc and tptc. Without the DT patches the driver will fall back to the legacy mode so things will work in a same way they did before. Or I can send a followup patch for edma.c, with that there is no need to add the HWMOD_INIT_NO_IDLE to hwmod and power management looks better. Basically I'm registering a 'dummy' driver for the edma3-tptc so omap hwmod code will not shut it down but we will keep the possibility to manage the power state still. -- P?ter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
