- * Note: I removed media-bay details from the feature stuff, I beleive it's
- * not worth it, the media-bay driver can directly use the mac-io
- * ASIC registers.
- *
- * Implementation note: Currently, none of these functions will block.
- * However, they may internally protect themselves with a spinlock
- * for way too long. Be prepared for at least some of these to block
- * in the future.
- *
- * Unless specifically defined, the result code is assumed to be an
- * error when negative, 0 is the default success result. Some functions
- * may return additional positive result values.
- *
- * To keep implementation simple, all feature calls are assumed to have
- * the prototype parameters (struct device_node* node, int value).
- * When either is not used, pass 0.
