- *
- * ---
- *
- * This driver supports the embedded UARTs of the Sharp LH7A40X series
- * CPUs. While similar to the 16550 and other UART chips, there is
- * nothing close to register compatibility. Moreover, some of the
- * modem control lines are not available, either in the chip or they

- * For simplicity, we disable the IR functions of any UART whenever
