According to the manual the DMA channels for UART7 to 10 are: uart7: 144 145 uart8: 146 147 uart9: 148 149 uart10: 150 151 Might as well add those too. We have uart 7 and 8 in use on our board so I am about to go test it. -- Len Sorensen -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
