net: phy: leds: Add support for "link" trigger

2017-11-08T01:24:14Z

Currently, we create a LED trigger for any link speed known to a PHY. These triggers only fire when their exact link speed had been negotiated (they aren't cumulative, that is, they don't fire for "their or any higher" link speed). What we are missing, however, is a trigger which will fire on any link speed known to the PHY. Such trigger can then be used for implementing a poor man's substitute of the "link" LED on boards that lack it. Let's add it. Signed-off-by: Maciej S. Szmigiero Signed-off-by: David S. Miller

net: phy: DP83822 initial driver submission

2017-10-11T21:14:32Z

Add support for the TI DP83822 10/100Mbit ethernet phy. The DP83822 provides flexibility to connect to a MAC through a standard MII, RMII or RGMII interface. In addition the DP83822 needs to be removed from the DP83848 driver as the WoL support is added here for this device.

net: phy: Kconfig: Fix PHY infrastructure menu in menuconfig

2017-09-19T20:46:43Z

Since the integration of PHYLINK, the configuration option which used to be under the PHY infrastructure menu in menuconfig ended up one level up (the network device driver section) By placing PHYLINK option right after PHYLIB entry, it broke the way Kconfig used to build the menu. See kconfig-language.txt, section "Menu structure", 2nd method. This is fixed by placing the PHYLINK option just before PHYLIB.

sfp: add SFP module support

2017-08-07T03:55:29Z

Add support for SFP hotpluggable modules via sfp-bus and phylink. This supports both copper and optical SFP modules, which require different Serdes modes in order to properly negotiate the link. Optical SFP modules typically require the Serdes link to be talking 1000BaseX mode - this is the gigabit ethernet mode defined by the 802.3 standard. Copper SFP modules typically integrate a PHY in the module to convert from Serdes to copper, and the PHY will be configured by the vendor to either present a 1000BaseX Serdes link (for fixed 1000BaseT) or a SGMII Serdes link. However, this is vendor defined, so we instead detect the PHY, switch the link to SGMII mode, and use traditional PHY based negotiation. Signed-off-by: Russell King Signed-off-by: David S. Miller

phylink: add phylink infrastructure

2017-08-07T03:55:29Z

The link between the ethernet MAC and its PHY has become more complex as the interface evolves. This is especially true with serdes links, where the part of the PHY is effectively integrated into the MAC. Serdes links can be connected to a variety of devices, including SFF modules soldered down onto the board with the MAC, a SFP cage with a hotpluggable SFP module which may contain a PHY or directly modulate the serdes signals onto optical media with or without a PHY, or even a classical PHY connection. Moreover, the negotiation information on serdes links comes in two varieties - SGMII mode, where the PHY provides its speed/duplex/flow control information to the MAC, and 1000base-X mode where both ends exchange their abilities and each resolve the link capabilities. This means we need a more flexible means to support these arrangements, particularly with the hotpluggable nature of SFP, where the PHY can be attached or detached after the network device has been brought up. Ethtool information can come from multiple sources: - we may have a PHY operating in either SGMII or 1000base-X mode, in which case we take ethtool/mii data directly from the PHY. - we may have a optical SFP module without a PHY, with the MAC operating in 1000base-X mode - the ethtool/mii data needs to come from the MAC. - we may have a copper SFP module with a PHY whic can't be accessed, which means we need to take ethtool/mii data from the MAC. Phylink aims to solve this by providing an intermediary between the MAC and PHY, providing a safe way for PHYs to be hotplugged, and allowing a SFP driver to reconfigure the serdes connection. Phylink also takes over support of fixed link connections, where the speed/duplex/flow control are fixed, but link status may be controlled by a GPIO signal. By avoiding the fixed-phy implementation, phylink can provide a faster response to link events: fixed-phy has to wait for phylib to operate its state machine, which can take several seconds. In comparison, phylink takes milliseconds.

net: phy: add I2C mdio bus

2017-08-07T03:55:28Z

Add an I2C MDIO bus bridge library, to allow phylib to access PHYs which are connected to an I2C bus instead of the more conventional MDIO bus. Such PHYs can be found in SFP adapters and SFF modules. Since PHYs appear at I2C bus address 0x40..0x5f, and 0x50/0x51 are reserved for SFP EEPROMs/diagnostics, we must not allow the MDIO bus to access these I2C addresses.
