| 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. |
