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 canm 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.
