    serial: 8250_ingenic: support for Ingenic SoC UARTs · 0cf985f4
    Paul Burton authored
    Introduce a driver suitable for use with the UARTs present in
    Ingenic SoCs such as the JZ4740 & JZ4780. These are described as being
    ns16550 compatible but aren't quite - they require the setting of an
    extra bit in the FCR register to enable the UART module. The serial_out
    implementation is the same as that in arch/mips/jz4740/serial.c - which
    will shortly be removed.
