144 | /* PHY state machine states: | |
145 | * | |
146 | * DOWN: PHY device and driver are not ready for anything. probe | |
147 | * should be called if and only if the PHY is in this state, | |
148 | * given that the PHY device exists. | |
149 | * - PHY driver probe function will, depending on the PHY, set | |
150 | * the state to STARTING or READY | |
151 | * | |
152 | * STARTING: PHY device is coming up, and the ethernet driver is | |
153 | * not ready. PHY drivers may set this in the probe function. | |
154 | * If they do, they are responsible for making sure the state is | |
155 | * eventually set to indicate whether the PHY is UP or READY, | |
156 | * depending on the state when the PHY is done starting up. | |
157 | * - PHY driver will set the state to READY | |
158 | * - start will set the state to PENDING | |
159 | * | |
160 | * READY: PHY is ready to send and receive packets, but the | |
161 | * controller is not. By default, PHYs which do not implement | |
162 | * probe will be set to this state by phy_probe(). If the PHY | |
163 | * driver knows the PHY is ready, and the PHY state is STARTING, | |
164 | * then it sets this STATE. | |
165 | * - start will set the state to UP | |
166 | * | |
167 | * PENDING: PHY device is coming up, but the ethernet driver is | |
168 | * ready. phy_start will set this state if the PHY state is | |
169 | * STARTING. | |
170 | * - PHY driver will set the state to UP when the PHY is ready | |
171 | * | |
172 | * UP: The PHY and attached device are ready to do work. | |
173 | * Interrupts should be started here. | |
174 | * - timer moves to AN | |
175 | * | |
176 | * AN: The PHY is currently negotiating the link state. Link is | |
177 | * therefore down for now. phy_timer will set this state when it | |
178 | * detects the state is UP. config_aneg will set this state | |
179 | * whenever called with phydev->autoneg set to AUTONEG_ENABLE. | |
180 | * - If autonegotiation finishes, but there's no link, it sets | |
181 | * the state to NOLINK. | |
182 | * - If aneg finishes with link, it sets the state to RUNNING, | |
183 | * and calls adjust_link | |
184 | * - If autonegotiation did not finish after an arbitrary amount | |
185 | * of time, autonegotiation should be tried again if the PHY | |
186 | * supports "magic" autonegotiation (back to AN) | |
187 | * - If it didn't finish, and no magic_aneg, move to FORCING. | |
188 | * | |
189 | * NOLINK: PHY is up, but not currently plugged in. | |
190 | * - If the timer notes that the link comes back, we move to RUNNING | |
191 | * - config_aneg moves to AN | |
192 | * - phy_stop moves to HALTED | |
193 | * | |
194 | * FORCING: PHY is being configured with forced settings | |
195 | * - if link is up, move to RUNNING | |
196 | * - If link is down, we drop to the next highest setting, and | |
197 | * retry (FORCING) after a timeout | |
198 | * - phy_stop moves to HALTED | |
199 | * | |
200 | * RUNNING: PHY is currently up, running, and possibly sending | |
201 | * and/or receiving packets | |
202 | * - timer will set CHANGELINK if we're polling (this ensures the | |
203 | * link state is polled every other cycle of this state machine, | |
204 | * which makes it every other second) | |
205 | * - irq will set CHANGELINK | |
206 | * - config_aneg will set AN | |
207 | * - phy_stop moves to HALTED | |
208 | * | |
209 | * CHANGELINK: PHY experienced a change in link state | |
210 | * - timer moves to RUNNING if link | |
211 | * - timer moves to NOLINK if the link is down | |
212 | * - phy_stop moves to HALTED | |
213 | * | |
214 | * HALTED: PHY is up, but no polling or interrupts are done. Or | |
215 | * PHY is in an error state. | |
216 | * | |
217 | * - phy_start moves to RESUMING | |
218 | * | |
219 | * RESUMING: PHY was halted, but now wants to run again. | |
220 | * - If we are forcing, or aneg is done, timer moves to RUNNING | |
221 | * - If aneg is not done, timer moves to AN | |
222 | * - phy_stop moves to HALTED | |
