2015-09-24phy: fix mdiobus module safetyRussell King1-1/+4
Re-implement the mdiobus module refcounting to ensure that we actually ensure that the mdiobus module code does not go away while we might call into it. The old scheme using bus->dev.driver was buggy, because bus->dev is a class device which never has a struct device_driver associated with it, and hence the associated code trying to obtain a refcount did nothing useful. Instead, take the approach that other subsystems do: pass the module when calling mdiobus_register(), and record that in the mii_bus struct. When we need to increment the module use count in the phy code, use this stored pointer. When the phy is deteched, drop the module refcount, remembering that the phy device might go away at that point. This doesn't stop the mii_bus going away while there are in-use phys - it merely stops the underlying code vanishing. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: David S.

2015-08-31net: phy: Allow PHY devices to identify themselves as Ethernet switches, etc.Florian Fainelli1-0/+12
Some Ethernet MAC drivers using the PHY library require the hardcoding of link parameters when interfaced to a switch device, SFP module, switch to switch port, etc. This has typically lead to various ad-hoc implementations looking like this: - using a "fixed PHY" emulated device, which will provide link indication towards the Ethernet MAC driver and hardware - pretend there is no PHY and hardcode link parameters, ala mv643x_eth Based on that, it is desireable to have the PHY drivers advertise the correct link parameters, just like regular Ethernet PHYs towards their CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able to tell whether this link should be monitored or not. In the context of an Ethernet switch, SFP module, switch to switch link, we do not need to monitor this link since it should be always up.

2014-07-30net: libphy: Add phy specific function to access mmd phy registersVince Bridgers1-0/+18
libphy was originally written assuming all phy devices support clause 45 access extensions to the mmd registers through the indirection registers located within the first 16 phy registers. This assumption is not true in all cases, and one specific example is the Micrel ksz9021 10/100/1000 Mbps phy. Using the stmmac driver, accessing the mmd registers to query and configure energy efficient Ethernet (EEE) features yielded unexpected behavior. This patch adds mmd access functions to the phy driver that can be overriden by the phy specific driver if the phy does not support this mechanism or uses it's own non-standard access mechanism. By default, the IEEE Compatible clause 45 access mechanism described in clause 22 is used. With this patch, EEE query/configure functions as expected using the stmmac and the Micrel ksz9021 phy.

This commit adds the necessary definitions for the PHY layer to recognize "qsgmii" as a valid PHY interface. A QSMII interface, as defined at http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface, is "is a method of combining four SGMII lines into a 5Gbit/s interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX data and a single LVDS clock signal. QSGMII uses significantly fewer signal lines than four SGMII busses." This type of MAC <-> PHY connection might require special handling on the MAC driver side, so it should be possible to express this type of MAC <-> PHY connection, for example in the Device Tree.
