131 | /* |
132 | * Virtual registers. | |
133 | * Useful to support attributes which are not supported by standard PMBus | |
134 | * registers but exist as manufacturer specific registers on individual chips. | |
135 | * Must be mapped to real registers in device specific code. | |
136 | * | |
137 | * Semantics: | |
138 | * Virtual registers are all word size. | |
139 | * READ registers are read-only; writes are either ignored or return an error. | |
20fcfe17 GR |
140 | * RESET registers are read/write. Reading reset registers returns zero |
141 | * (used for detection), writing any value causes the associated history to be | |
142 | * reset. | |
143 | * Virtual registers have to be handled in device specific driver code. Chip | |
144 | * driver code returns non-negative register values if a virtual register is | |
145 | * supported, or a negative error code if not. The chip driver may return | |
146 | * -ENODATA or any other error code in this case, though an error code other | |
147 | * than -ENODATA is handled more efficiently and thus preferred. Either case, | |
148 | * the calling PMBus core code will abort if the chip driver returns an error | |
149 | * code when reading or writing virtual registers. | |
