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

net: phy: re-design phy_modes to be self-contained

2014-02-13T00:08:20Z

of_get_phy_mode() uses a local array to map phy_interface_t values from include/linux/net/phy.h to a string which is read from the 'phy-mode' or 'phy-connection-type' property. In preparation for exposing the PHY interface mode through sysfs, perform the following: - mode phy_modes from drivers/of/of_net.c to include/linux/phy.h such that it is right below the phy_interface_t enum - make it a static inline function returning the string such that we can use it by just including include/linux/net/phy.h - add a PHY_INTERFACE_MODE_MAX enum value to guard the iteration in of_get_phy_mode() Signed-off-by: Florian Fainelli Signed-off-by: David S.

net: phy: allow driver to implement their own aneg_done

2014-02-13T00:08:19Z

Some PHYs out there can be very quirky with respect to how they would report the auto-negotiation is completed. Allow drivers to override the generic aneg_done() implementation by providing their own. Since not all drivers have been updated yet to use genphy_aneg_done() as aneg_done() callback, we explicitely check that this callback is valid before calling into it.

net: phy: add genphy_aneg_done()

2014-02-13T00:08:19Z

In preparation for allowing PHY drivers to potentially override their auto-negotiation done callback, move the contents of phy_aneg_done() to genphy_aneg_done() since that function really is the generic implementation based on the BMSR_ANEGCOMPLETE status.

phylib: Support attaching to generic 10g driver

2014-01-13T22:29:49Z

phy_attach_direct() may now attach to a generic 10G driver. It can also be used exactly as phy_connect_direct(), which will be useful when using of_mdio, as phy_connect (and therefore of_phy_connect) start the PHY state machine, which is currently irrelevant for 10G PHYs.
