    USB: usbserial: mos7720: add support for parallel port on moschip 7715 · b69578df
    Mike Dunn authored
    Add support for the parallel port on the moschip MCS7715 device.  The port
    registers itself with the parport subsystem as a low-level driver.  A separate
    entry to the kernel configuration is added beneath that for the mos7720, to
    avoid the need to link with the parport subsystem code for users who don't have
    or don't want the parallel port.  Only compatibility mode is currently supported
    (no ECP/EPP).  Tested with both moschip devices (7720 and 7715) on UP and SMP
    hosts, including regression testing of serial port, concurrent operation of
    serial and parallel ports, and various connect / disconnect scenarios.
