We have already in /* * include/linux/serial_reg.h * #define UART_RX 0 /* In: Receive buffer */ #define UART_TX 0 /* Out: Transmit buffer */ #define UART_IER 1 /* Out: Interrupt Enable Register */ #define UART_IIR 2 /* In: Interrupt ID Register */ #define UART_FCR 2 /* Out: FIFO Control Register */ #define UART_LCR 3 /* Out: Line Control Register */ #define UART_MCR 4 /* Out: Modem Control Register */ #define UART_LSR 5 /* In: Line Status Register */ #define UART_MSR 6 /* In: Modem Status Register */ #define UART_SCR 7 /* I/O: Scratch Register */ and the bit definitions, as well. -- 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
