- * Ported to Linux 2.6 by Hong-Gunn Chew with the help of Jean Delvare
- * and advice of Greg Kroah-Hartman.
- *
- * Notes about the port:
- * Release 0x00 of the GL518SM chipset doesn't support reading of in0,
- * in1 nor in2. The original driver had an ugly workaround to get them
- * anyway (changing limits and watching alarms trigger and wear off).
- * We did not keep that part of the original driver in the Linux 2.6
- * version, since it was making the driver significantly more complex
- * with no real benefit.
- *
- * History:
- * 2004-01-28 Original port. (Hong-Gunn Chew)
- * 2004-01-31 Code review and approval. (Jean Delvare)
