2019-04-15	net: phy: switch drivers to use dynamic feature detection	Heiner Kallweit	1	-10/+10
	Recently genphy_read_abilities() has been added that dynamically detects clause 22 PHY abilities. I think this detection should work with all supported PHY's, at least for the ones with basic features sets, i.e. PHY_BASIC_FEATURES and PHY_GBIT_FEATURES. So let's remove setting these features explicitly and rely on phylib feature detection. I don't have access to most of these PHY's, therefore I'd appreciate regression testing. v2: - make the feature constant a comment so that readers know which features are supported by the respective PHY Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Tested-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2019-01-22	net: phy: Convert some PHY and MDIO driver files to SPDX headers	Andrew Lunn	1	-10/+1
	Where the license text and the MODULE_LICENSE() value agree, convert to using an SPDX header, removing the license text. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-11-11	net: phy: remove flag PHY_HAS_INTERRUPT from driver configs	Heiner Kallweit	1	-10/+0
	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 <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

	The phys embedded into the v1.1 of the VR9 SoC are using different phy ids. Add the phy ids to use the driver for this VR9 version as well. Signed-off-by: Mathias Kresin <dev@kresin.me> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-12-10	net: phy: phy drivers should not set SUPPORTED_[Asym_]Pause	Timur Tabi	1	-16/+8
	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.
