Not every ARCH_MXC supports MXS DMA. For example mx27/25/31/35/50/51/53 do not have the mxs dma block. > But then, is it a problem if we allow to enable a driver although not > available in a certain SoC? I don't think it is a problem. Currently we do the same for the sdma driver. IMX_SDMA also contains 'depends on ARCH_MXC' even though not all ARCH_MXC has the the SDMA engine. mx27, for example does not have it, so this proposal seems safe. -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
