The first patch adds support for cyclic transfers usable for audio. There is a similar approach implemented for the dw_dmac, this patch instead adds the cyclic transfers to the dmaengine API. Other patches not posted here are necessary to actually make use of the SDMA engine. Please pull the following branch if you want to test these patches. The branch includes mxcmmc support for the i.MX31 based on SDMA and i.MX35-3stack audio support (sgtl5000 codec): http://git.pengutronix.de/git/imx/linux-2.6.git sdma-sdmaengine For generating firmware images for the SDMA engine look at http://git.pengutronix.de/git/imx/sdma-firmware.git Sascha -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
