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.
That's just plain gross and horrible. You could use phandles you know :-)
Or you could use path in your strings, or something like that.
Note that any time you have a struct device, you have a free device_node pointer as well.
