net: phy: fix auto-negotiation stall due to unavailable interrupt

2017-04-26T18:32:00Z

The Ethernet link on an interrupt driven PHY was not coming up if the Ethernet cable was plugged before the Ethernet interface was brought up. The patch trigger PHY state machine to update link state if PHY was requested to do auto-negotiation and auto-negotiation complete flag already set. During power-up cycle the PHY do auto-negotiation, generate interrupt and set auto-negotiation complete flag. Interrupt is handled by PHY state machine but doesn't update link state because PHY is in PHY_READY state. After some time MAC bring up, start and request PHY to do auto-negotiation. If there are no new settings to advertise genphy_config_aneg() doesn't start PHY auto-negotiation. PHY continue to stay in auto-negotiation complete state and doesn't fire interrupt. At the same time PHY state machine expect that PHY started auto-negotiation and is waiting for interrupt from PHY and it won't get it.

net: phy: Do not perform software reset for Generic PHY

2017-03-06T01:57:27Z

The Generic PHY driver is a catch-all PHY driver and it should preserve whatever prior initialization has been done by boot loader or firmware agents. For specific PHY device configuration it is expected that a specialized PHY driver would take over that role. Resetting the generic PHY was a bad idea that has lead to several complaints and downstream workarounds e.g: in OpenWrt/LEDE so restore the behavior prior to 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()").

net: phy: Check phydev->drv

2017-02-20T15:15:11Z

There are number of function calls, originating from user-space, typically through the Ethernet driver that can make us crash by dereferencing phydev->drv which will be NULL once we unbind the driver from the PHY. There are still functional issues that prevent an unbind then rebind to work, but these will be addressed separately.

net: phy: Allow pre-declaration of MDIO devices

2017-02-07T15:51:46Z

Allow board support code to collect pre-declarations for MDIO devices by registering them with mdiobus_register_board_info(). SPI and I2C buses have a similar feature, we were missing this for MDIO devices, but this is particularly useful for e.g: MDIO-connected switches which need to provide their port layout (often board-specific) to a MDIO Ethernet switch driver.
