net: phy: workaround for buggy cable detection by LAN8700 after cable plugging

2015-08-17T21:27:23Z

* Due to HW bug, LAN8700 sometimes does not detect presence of energy in the Ethernet cable in Energy Detect Power-Down mode (e.g while EDPWRDOWN bit is set, the ENERGYON bit does not asserted sometimes). This is a common bug of LAN87xx family of PHY chips. * The lan87xx_read_status() was improved to acquire ENERGYON bit. Its previous algorythm still not reliable on 100 % and sometimes skip cable plugging. Signed-off-by: Igor Plyatov Signed-off-by: David S. Miller

net: phy: replace phy_drivers_register calls

2014-11-12T18:52:53Z

Replace module init/exit which only calls phy_drivers_register with module_phy_driver macro. Tested using Micrel driver, and otherwise compile-tested only. Signed-off-by: Johan Hovold Signed-off-by: David S. Miller

net: phy: smsc: move smsc_phy_config_init reset part in a soft_reset function

2014-08-17T03:15:54Z

On the one hand, phy_device.c provides a generic reset function if the phy driver does not provide a soft_reset pointer. This generic reset does not take into account the state of the phy, with a potential failure if the phy is in powerdown mode. On the other hand, smsc driver provides a function with both correct reset behaviour and configuration. This patch moves the reset part into a new smsc_phy_reset function and provides the soft_reset pointer to have a correct reset behaviour by default.

net: phy: smsc: force all capable mode if the phy is started in powerdown mode

2012-12-07T17:48:00Z

A SMSC PHY in power down mode can't be used. If a SMSC PHY is in this mode in the config_init stage, the mode "all capable" is set. So the PHY could then be used. Signed-off-by: Philippe Reynes Signed-off-by: David S. Miller

net: phy: smsc: Re-enable EDPD mode for LAN87xx

2012-11-15T22:48:50Z

This patch re-enables Energy Detect Power Down (EDPD) mode for the LAN8710/LAN8720. EDPD mode was disabled in a previous commit, (b629820d18fa65cc598390e4b9712fd5f83ee693), because it was causing the PHY to not be able to detect a link when cold started without a cable connected. The LAN8710/LAN8720 requires a minimum of 2 link pulses within 64ms of each other in order to set the ENERGYON bit and exit EDPD mode. If a link partner does send the pulses within this interval, the PHY will remained powered down. This workaround will manually toggle the PHY on/off upon calls to read_status in order to generate link test pulses if the link is down. If a link partner is present, it will respond to the pulses, which will cause the ENERGYON bit to be set and will cause the EDPD mode to be exited.

net: phy: smsc: Implement PHY config_init for LAN87xx

2012-09-27T22:28:30Z

The LAN8710/LAN8720 chips do have broken the "FlexPWR" smart power-saving capability. Enabling it leads to the PHY not being able to detect Link when cold-started without cable connected. Thus, make sure this is disabled. Signed-off-by: Marek Vasut Cc: Christian Hohnstaedt Cc: David S.
