Glad to see this happening! No luck here though, after a quick test I'm getting the following with MMC not working: zoom3 [ 2.277160] omap_hsmmc omap_hsmmc.1: unable to obtain RX DMA engine channel 48 [ 2.284729] omap_hsmmc omap_hsmmc.2: unable to obtain RX DMA engine channel 78 [ 2.292999] omap_hsmmc omap_hsmmc.0: unable to obtain RX DMA engine channel 62 blaze [ 1.681610] omap_hsmmc omap_hsmmc.1: unable to obtain RX DMA engine channel 48 [ 1.689331] omap_hsmmc omap_hsmmc.0: unable to obtain RX DMA engine channel 62 [ 1.697174] omap_hsmmc omap_hsmmc.4: unable to obtain RX DMA engine channel 60 n900 [ 2.492248] omap_hsmmc omap_hsmmc.0: unable to obtain RX DMA engine channel 62 [ 2.500488] omap_hsmmc omap_hsmmc.1: unable to obtain RX DMA engine channel 48 And leaving out patch 7/8 produces similar errors for both rx and tx, but MMC works without DMA: n900 [ 2.478363] omap_hsmmc omap_hsmmc.0: unable to obtain RX DMA engine channel 62 [ 2.486267] omap_hsmmc omap_hsmmc.0: unable to obtain TX DMA engine channel 61 [ 2.718322] omap_hsmmc omap_hsmmc.1: unable to obtain RX DMA engine channel 48 [ 2.726135] omap_hsmmc omap_hsmmc.1: unable to obtain TX DMA engine channel 47 Regards, Tony -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
