OK, I realize its also unnecessary to allocate save anything. In your new version when you respin, please just recreate the state based on the in-memory kernel data structures already there. Ex, you know which channels were allocated so you just set those bits in the IESR. > (And the 'v3' in the subject is really my bad, sorry - I only sent one > version of this patch ever). > > I can respin the patch on top of the proper driver once all the edma > bits have eventually been moved to drivers/dma.

The work is waiting on conversion of the davinci-pcm ASoC driver to DMA Engine, which once done can make exposing the private EDMA API in arch/arm/common/edma.c obsolete and we can take it to drivers/dma. Some more work to be done in edma in unifying the probe etc. thanks, -Joel -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
