net: phy: remove flag PHY_HAS_INTERRUPT from driver configs

2018-11-11T17:36:56Z

Now that flag PHY_HAS_INTERRUPT has been replaced with a check for callbacks config_intr and ack_interrupt, we can remove setting this flag from all driver configs. Last but not least remove flag PHY_HAS_INTERRUPT completely. Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: Add phydev_warn()

2018-10-02T05:55:35Z

Not all new style LINK_MODE bits can be converted into old style SUPPORTED bits. We need to warn when such a conversion is attempted. Add a helper for this. Convert all pr_warn() calls to phydev_warn() where possible. Signed-off-by: Andrew Lunn Reviewed-by: Maxime Chevallier Signed-off-by: David S. Miller

lan78xx: Read LED states from Device Tree

2018-04-20T15:39:09Z

Add support for DT property "microchip,led-modes", a vector of zero to four cells (u32s) in the range 0-15, each of which sets the mode for one of the LEDs. Some possible values are: 0=link/activity 1=link1000/activity 2=link100/activity 3=link10/activity 4=link100/1000/activity 5=link10/1000/activity 6=link10/100/activity 14=off 15=on These values are given symbolic constants in a dt-bindings header. Also use the presence of the DT property to indicate that the LEDs should be enabled - necessary in the event that no valid OTP or EEPROM is available.

net: phy: Remove residual magic from PHY drivers

2017-05-16T19:58:18Z

commit fa8cddaf903c ("net phylib: Remove unnecessary condition check in phy") removed the only place where the PHY flag PHY_HAS_MAGICANEG was checked. But it left the flag being set in the drivers. Remove the flag. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: phy drivers should not set SUPPORTED_[Asym_]Pause

2016-12-11T04:31:19Z

Instead of having individual PHY drivers set the SUPPORTED_Pause and SUPPORTED_Asym_Pause flags, phylib itself should set those flags, unless there is a hardware erratum or other special case. During autonegotiation, the PHYs will determine whether to enable pause frame support. Pause frames are a feature that is supported by the MAC. It is the MAC that generates the frames and that processes them. The PHY can only be configured to allow them to pass through. This commit also effectively reverts the recently applied c7a61319 ("net: phy: dp83848: Support ethernet pause frames"). So the new process is: 1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in phydev->supported. This indicates that the PHY supports pause frames. 2) The MAC driver checks phydev->supported before it calls phy_start(). If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver sets those bits in phydev->advertising, if it wants to enable pause frame support. 3) When the link state changes, the MAC driver checks phydev->pause and phydev->asym_pause, If the bits are set, then it enables the corresponding features in the MAC. The algorithm is: if (phydev->pause) The MAC should be programmed to receive and honor pause frames it receives, i.e. enable receive flow control. if (phydev->pause != phydev->asym_pause) The MAC should be programmed to transmit pause frames when needed, i.e. enable transmit flow control.
