- * Module command line parameters:
- *
- * Supported devices:
- * /dev/dsp standard OSS /dev/dsp device
- * /dev/mixer standard OSS /dev/mixer device
- *
- * Notes:
- *
- * 1. Much of the OSS buffer allocation, ioctl's, and mmap'ing are
- * taken, slightly modified or not at all, from the ES1371 driver,
- * so refer to the credits in es1371.c for those. The rest of the
- * code (probe, open, read, write, the ISR, etc.) is new.
- * 2. The following support is untested:
- * * Memory mapping the audio buffers, and the ioctl controls that go
- * with it.
- * * S/PDIF output.
- * * I2S support.
- * 3. The following is not supported:
- * * legacy audio mode.
- * 4. Support for volume button interrupts is implemented but doesn't
- * work yet.
- *
- * Revision history
- * 02.08.2001 Initial release
- * 06.22.2001 Added I2S support
- * 07.30.2003 Removed initialisation to zero for static variables
- * (spdif[NR_DEVICE], i2s_fmt[NR_DEVICE], and devindex)
