94 driver provides support for the Byte Runner Technologies TC-400
95 and TC-800 series boards that multiplex together up to four or eight
100 communications interfaces.
104 device is the master device for up to eight
106 devices. The kernel configuration specifies these
108 devices as slave devices of the
110 device, as shown in the synopsis. The slave ID given for each
112 device determines which bit in the interrupt multiplexing register is
113 tested to find interrupts for that device.
116 specification for the
118 device is used to compute the base addresses for the
120 subdevices and the port for the interrupt multiplexing register.
122 Not all possible configuration options are currently supported (for
123 example, speeds beyond 115200 baud are not currently supported).
133 driver was written by Jukka Marin.
