|  * Note: I removed media-bay details from the feature stuff, I believe 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.
