net: phy: export phy_{read,write}_mmd_indirect

2014-08-23T18:39:09Z

Some PHY drivers might need to access Clause 45 registers in Clause 22 compatibility mode to e.g: properly advertise EEE support when disabled by default. Export these two helper functions: phy_read_mmd_indirect() and phy_write_mmd_indirect() for drivers to use them. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: libphy: Add phy specific function to access mmd phy registers

2014-07-31T03:00:21Z

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.

net: phylib: add link_change_notify callback to phy device

2014-06-21T22:50:00Z

Add a notify callback to inform phy drivers when the core is about to do its link adjustment. No change for drivers that do not implement this callback. Signed-off-by: Daniel Mack Signed-off-by: David S. Miller

mdio_bus: implement devm_mdiobus_alloc/devm_mdiobus_free

2014-05-02T20:16:26Z

Add a resource managed devm_mdiobus_alloc[_size]()/devm_mdiobus_free() to automatically clean up MDIO bus alocations made by MDIO drivers, thus leading to simplified MDIO drivers code.

net: phy: export genphy_config_init()

2014-04-20T22:18:54Z

This enables other drivers to call this generic implementation, and then only do specific details on top of it. Signed-off-by: Daniel Mack Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: add minimal support for QSGMII PHY

2014-04-16T18:36:12Z

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.

net: phy: allow PHY drivers to implement their own software reset

2014-02-17T21:40:09Z

As pointed out by Shaohui, most 10G PHYs out there have a non-standard compliant software reset sequence, eventually something much more complex than just toggling the BMCR_RESET bit. Allow PHY driver to implement their own soft_reset() callback to deal with that. If no callback is provided, call into genphy_soft_reset() which makes sure the existing behavior is kept intact.

net: phy: move PHY software reset to genphy_soft_reset

2014-02-17T21:40:08Z

As pointed out by Shaohui, this function is generic for 10/100/1000 PHYs, but 10G PHYs might have a slightly different reset sequence which prevents most of them from using this function. Move the BMCR_RESET based software resent sequence to genphy_soft_reset() in preparation for allowing PHY drivers to implement a soft_reset() callback.

net: phy: add MoCA PHY type

2014-02-14T05:27:57Z

Some Ethernet MACs are connected to a MoCA PHY which will handle the low-level job of sending Ethernet frames on the coaxial cable, these Ethernet MACs need to know about it to be properly configured. Add a new PHY mode "moca" and update the Device Tree parsing logic to look for it. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: add "has_fixups" boolean property

2014-02-13T00:08:20Z

Add a boolean property which indicates if the PHY has had any fixup routine ran on it. We are later going to use that boolean to expose it as a sysfs property to help troubleshooting. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller
