With some further experimentation I've found that making the esp/le devices children of their respective espdma/ledma devices makes things a lot cleaner. I've also got another related patch to update the espdma/ledma tracepoints to log the DMA transaction length, so I'll submit a v2 of this with the additional changes shortly. ATB, Mark.
