+
+ Module for Conexant Riptide chip
+
+ joystick_port - Joystick port # (default: 0x200)
+ mpu_port - MPU401 port # (default: 0x330)
+ opl3_port - OPL3 port # (default: 0x388)
+
+ This module supports multiple cards.
+ The driver requires the firmware loader support on kernel.
+ You need to install the firmware file "riptide.hex" to the standard
+ firmware path (e.g. /lib/firmware).
