They have to exist in the DTS first, and I'm loathe to modify the DTS.
Can you not dynamically assign an id? If alsa soc needs a unique id number, then just create a lookup function. Something like of_asoc_phandle_to_codec_id() that will either return a previously assigned id, or will assign a new id. You shouldn't ever need to add data to the tree at runtime. g. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
