- * sound/oss/ad1848.c
- *
- * The low level driver for the AD1848/CS4248 codec chip which
- * is used for example in the MS Sound System.
- *
- * The CS4231 which is used in the GUS MAX and some other cards is
- * upwards compatible with AD1848 and this driver is able to drive it.
- *
- * CS4231A and AD1845 are upward compatible with CS4231. However
- * the new features of these chips are different.
- *
- * CS4232 is a PnP audio chip which contains a CS4231A (and SB, MPU).
- * CS4232A is an improved version of CS4232.

- *
- *
- * Thomas Sailer : ioctl code reworked (vmalloc/vfree removed)
- * general sleep/wakeup clean up.
- * Alan Cox : reformatted. Fixed SMP bugs. Moved to kernel alloc/free
- * of irqs. Use dev_id.
- * Christoph Hellwig : adapted to module_init/module_exit
- * Aki Laukkanen : added power management support
- * Arnaldo C. de Melo : added missing restore_flags in ad1848_resume
- * Miguel Freitas : added ISA PnP support
- * Alan Cox : Added CS4236->4239 identification
- * Daniel T. Cobra : Alernate config/mixer for later chips
- * Alan Cox : Merged chip idents and config code
- *
- * TODO
- * APM save restore assist code on IBM thinkpad
- *
- * Status:
- * Tested. Believed fully functional.
