* 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.
