You want something like "depends on FSL_SOC && !(FSL_DMA || FSL_DMA=m)" However, the more problematic option is ASYNC_TX_CHANNEL_SWITCH. That option is problematic for RAID, so I propose "depend on !ASYNC_TX_CHANNEL_SWITCH" since that addresses both problems. -- 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
