8 [from pmbus.org] The Power Management Bus (PMBus) is an open standard
18 promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters
21 Unfortunately, while PMBus commands are standardized, there are no mandatory
23 Also, different PMBUs devices act differently if non-supported commands are
27 Despite all those difficulties, a generic PMBus device driver is still useful
29 device specific extensions in addition to the core PMBus driver, since it is
30 simply unknown what new device specific functionality PMBus device developers
34 to modify the core PMBus driver repeatedly for new devices, the PMBus driver was
