*
* 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.
