This will result in moving away from the CK_* flags. There are some previous public mailing list messages on this topic that you can probably find by searching for CK_446X. Now that we've switched to the common clock framework, it should be more practical to do this conversion, since we can refer to parent clocks by name rather than by pointer. Could you please update your patch to take that approach instead? Thanks for your feedback. I am in the process of removing all the CK_* flags and making separate lists instead. I am not Able to figure out where/how exactly the flag "CK_TI816X" Is getting used. Which family of processors are chosen Using this flag? Which clock nodes are selected using This flag? - Paul Regards, Keerthy -- 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
