Don't reset the phy without respect to the PHY library state machine because this breaks the phy IRQ mode. The same behaviour can be archived now by specifying the refclk.

2020-09-09net: phy: smsc: LAN8710/20: add phy refclk in supportMarco Felsch1-0/+25
Add support to specify the clock provider for the PHY refclk and don't rely on 'magic' host clock setup. [1] tried to address this by introducing a flag and fixing the corresponding host. But this commit breaks the IRQ support since the irq setup during .config_intr() is thrown away because the reset comes from the side without respecting the current PHY state within the PHY library state machine. Furthermore the commit fixed the problem only for FEC based hosts other hosts acting like the FEC are not covered. This commit goes the other way around to address the bug fixed by [1]. Instead of resetting the device from the side every time the refclk gets (re-)enabled it requests and enables the clock till the device gets removed. Now the PHY library is the only place where the PHY gets reset to respect the PHY library state machine.

Generally, each PHY has their own configuration and it can be done through an external PHY driver. The smsc95xx driver uses only the hard-coded internal PHY configuration.

2020-06-22net: phy: smsc: fix printing too many logsDejin Zheng1-4/+7
Commit 7ae7ad2f11ef47 ("net: phy: smsc: use phy_read_poll_timeout() to simplify the code") will print a lot of logs as follows when Ethernet cable is not connected: [ 4.473105] SMSC LAN8710/LAN8720 2188000.ethernet-1:00: lan87xx_read_status failed: -110 When wait 640 ms for check ENERGYON bit, the timeout should not be regarded as an actual error and an error message also should not be printed. due to a hardware bug in LAN87XX device, it leads to unstable detection of plugging in Ethernet cable when LAN87xx is in Energy Detect Power-Down mode. the workaround for it involves, when the link is down, and at each read_status() call: - disable EDPD mode, forcing the PHY out of low-power mode - waiting 640ms to see if we have any energy detected from the media - re-enable entry to EDPD mode This is presumably enough to allow the PHY to notice that a cable is connected, and resume normal operations to negotiate with the partner. The problem is that when no media is detected, the 640ms wait times out and this commit was modified to prints an error message. it is an inappropriate conversion by used phy_read_poll_timeout() to introduce this bug. so fix this issue by use read_poll_timeout() to replace phy_read_poll_timeout().

2016-12-10net: phy: phy drivers should not set SUPPORTED_[Asym_]PauseTimur Tabi1-12/+6
Instead of having individual PHY drivers set the SUPPORTED_Pause and SUPPORTED_Asym_Pause flags, phylib itself should set those flags, unless there is a hardware erratum or other special case. During autonegotiation, the PHYs will determine whether to enable pause frame support. Pause frames are a feature that is supported by the MAC. It is the MAC that generates the frames and that processes them. The PHY can only be configured to allow them to pass through. This commit also effectively reverts the recently applied c7a61319 ("net: phy: dp83848: Support ethernet pause frames"). So the new process is: 1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in phydev->supported. This indicates that the PHY supports pause frames. 2) The MAC driver checks phydev->supported before it calls phy_start(). If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver sets those bits in phydev->advertising, if it wants to enable pause frame support. 3) When the link state changes, the MAC driver checks phydev->pause and phydev->asym_pause, If the bits are set, then it enables the corresponding features in the MAC. The algorithm is: if (phydev->pause) The MAC should be programmed to receive and honor pause frames it receives, i.e. enable receive flow control. if (phydev->pause != phydev->asym_pause) The MAC should be programmed to transmit pause frames when needed, i.e. enable transmit flow control.

2016-06-10net: phy: smsc: reintroduced unconditional soft resetManfred Schlaegl1-13/+4
We detected some problems using the smsc lan8720a in combination with i.MX28 and tracked this down to commit 21009686662f ("net: phy: smsc: move smsc_phy_config_init reset part in a soft_reset function") With 2100968666 the generic soft reset is replaced by a specific function which handles power down state correctly. But additionally the soft reset itself got conditional and is therefore also only performed if the phy is in power down state. This patch keeps the conditional wake up from power down, but re-introduces the unconditional soft reset using the generic soft reset function. It was tested on linux-4.1.25 and linux-4.7.0-rc2.

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.
