Yes - and I may yet implement a "soft PDC" device if this turns out to be more than a 'quirk' for a very small number of device. But like you say - it doesn't need to be (and shouldn't be) in the actual device tree. For now though I think the code Nicolas has written works well enough and it's only really worth 'fixing' if we end up with too many 'quirky' devices. Steve
