Here I have a problem about blackfin TDM. After a deep sleep(all suspend to memory and most parts power-down), If codec resumes at first, clock ans sync are provided by it at onece. Then while CPU TDM interface resumes, it will fail to go back to right status for work.

What trouble does this give the TDM stuff? It sounds very fragile if things get confused like this (presumably as a result of having the clocks running).
