net: phy: Add phy_interface_is_rgmii helper

2015-05-27T04:27:35+00:00

RGMII interfaces come in 4 different flavors that the PHY library needs to care about: regular RGMII (no delays), RGMII with either RX or TX delay, and both. In order to avoid errors of checking only for one type of RGMII interface and miss the 3 others, introduce a convenience function which tests for all values. Suggested-by: David S.

net: phy: Add phy_ignore_ta_mask to account for broken turn-around

2015-05-14T17:40:55+00:00

Some PHY devices/switches will not release the turn-around line as they should do at the end of a MDIO transaction. To help with such situations, allow MDIO bus drivers to be made aware of such restrictions. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: keep track of the PHY suspend state

2015-01-27T08:16:51+00:00

In order to avoid double calls to phydev->drv->suspend and resume, keep track of whether the PHY has already been suspended as a consequence of a successful call to phy_suspend(). We will use this in our MDIO bus suspend/resume hooks to avoid a double suspend call. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: document has_fixups field

2015-01-27T08:16:51+00:00

has_fixups was introduced to help keeping track of fixups/quirks running on a PHY device, but we did not update the comment above struct phy_device accordingly. Fixes: b0ae009f3dc14 (net: phy: add "has_fixups" boolean property") Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

ethtool: Extend ethtool plugin module eeprom API to phylib

2015-01-06T22:16:55+00:00

This patch extends the ethtool plugin module eeprom API to support cards whose phy support is delegated to a separate driver. The handlers for ETHTOOL_GMODULEINFO and ETHTOOL_GMODULEEEPROM call the module_info and module_eeprom functions if the phy driver provides them; otherwise the handlers call the equivalent ethtool_ops functions provided by network drivers with built-in phy support.

net: phy: add static data field to struct phy_driver

2014-11-21T19:08:55+00:00

Add static driver-data field to struct phy_driver, which can be used to store structured device-type information. Signed-off-by: Johan Hovold Signed-off-by: David S. Miller

net: phy: add module_phy_driver macro

2014-11-12T18:52:52+00:00

Add helper macro for PHY drivers which do not do anything special in module init/exit. This will allow us to eliminate a lot of boilerplate code. Signed-off-by: Johan Hovold Signed-off-by: David S. Miller

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

2014-08-23T18:39:09+00:00

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

2014-07-31T03:00:21+00:00

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

2014-06-21T22:50:00+00:00

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
