What I need is something like a hashing function that can convert a "struct device_node *" into an "int". I'm going to have two functions that independently parse the device tree and locate a specific node. Both functions will "register the node" with asoc, but they'll use an integer ID to uniquely identify the node. At least, that's the way ASoC likes to operate. AsoC takes a fixed string plus a unique integer. I could technically create a unique string for each DMA device, and have the integer always be 0. > Something like > of_asoc_phandle_to_codec_id() that will either return a previously > assigned id, or will assign a new id.

It just would have been nice if my nodes already had phandles in them. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
