-Crystal SoundFusion CS4610/CS4612/CS461 joystick
-================================================
-
-Preface
--------
-
-This is a new low-level driver to support analog joystick attached to
-Crystal SoundFusion CS4610/CS4612/CS4615. This code is based upon
-Vortex/Solo drivers as an example of decoration style, and ALSA
-0.5.8a kernel drivers as an chipset documentation and samples.
-
-This version does not have cooked mode support; the basic code
-is present here, but have not tested completely. The button analysis
-is completed in this mode, but the axis movement is not.
-
-Raw mode works fine with analog joystick front-end driver and cs461x
-driver as a backend. I've tested this driver with CS4610, 4-axis and
-4-button joystick; I mean the jstest utility. Also I've tried to
-play in xracer game using joystick, and the result is better than
-keyboard only mode.
-
-The sensitivity and calibrate quality have not been tested; the two
-reasons are performed: the same hardware cannot work under Win95 (blue
-screen in VJOYD); I have no documentation on my chip; and the existing
-behavior in my case was not raised the requirement of joystick calibration.
-So the driver have no code to perform hardware related calibration.
-
-The patch contains minor changes of Config.in and Makefile files. All
-needed code have been moved to one separate file cs461x.c like ns558.c
-This driver have the basic support for PCI devices only; there is no
-ISA or PnP ISA cards supported. AFAIK the ns558 have support for Crystal
-ISA and PnP ISA series.
-
-The driver works with ALSA drivers simultaneously. For example, the xracer
-uses joystick as input device and PCM device as sound output in one time.
-There are no sound or input collisions detected. The source code have
-comments about them; but I've found the joystick can be initialized
-separately of ALSA modules. So, you can use only one joystick driver
-without ALSA drivers. The ALSA drivers are not needed to compile or
-run this driver.
-
-There are no debug information print have been placed in source, and no
-specific options required to work this driver. The found chipset parameters
-are printed via printk(KERN_INFO "..."), see the /var/log/messages to
-inspect cs461x: prefixed messages to determine possible card detection
-errors.

-Regards,
-Viktor
