Hi In the kernel config i can build the 8250_pci driver as module. So I can switch on (with loading module) the ValleyView LPIO1/2 HSUART Controller when I need it, and not always at startup. That is exactly what I want. But I need to change the device name from ttySx to my name like "ttyHSUARTx" only for this pci device and not for the other uart devices which is also controlled by the 8250. See: tty/serial/8250 /8250_core -> uart -> ttySx <- the naming are untouched /8250_pci -> hsuart ->ttyHSUARTx <- only here I will set another device name I'm not sure what is the right way to do that. Or is this not possible? --- Best regards Alexander -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
