Yeah if it's part of the MMC controller it makes no sense to separate it. So then the conecrns are using alternate DMA implementations and keeping PM runtime working :) BTW, Felipe mentioned that the best thing to do in the long run would be to set up sdhci-omap.c operating in ADMA mode. Felipe, care to summarize what you had in mind? Regards, Tony
