2019-02-24net: dsa: microchip: prepare PHY for proper advertisementTristram Ha
Prepare PHY for proper advertisement as sometimes the PHY in the switch has its own problems even though it may share the PHY id from regular PHY but the fixes in the PHY driver do not apply.

2019-02-24net: phy: marvell10g: add support for the 88x2110 PHYMaxime Chevallier
This patch adds support for the 88x2110 PHY, which is similar to the already supported 88x3310 PHY without the SFP interface. It supports 10/100/1000BASET along with 2.5GBASET, 5GBASET and 10GBASET, with the same interface modes that are used by the 3310. This PHY don't have the same issue as the 88x3310 regarding 2.5/5G abilities, and correctly follows the 802.3bz standard to list the supported abilities.

2019-02-24net: phy: marvell10g: Force reading of 2.5/5GMaxime Chevallier
As per 802.3bz, if bit 14 of (1.11) "PMA Extended Abilities" indicates whether or not we should read register (1.21) "2.52/5G PMA Extended Abilities", which contains information on the support of 2.5GBASET and 5GBASET. After testing on several variants of PHYS of this family, it appears that bit 14 in (1.11) isn't always set when it should be. PHYs 88X3310 (on MacchiatoBin) and 88E2010 do support 2.5G and 5GBASET, but don't have 1.11.14 set. Their register 1.21 is filled with the correct values, indicating 2.5G and 5G support. PHYs 88E2110 do have their 1.11.14 bit set, as it should. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

The Marvell Alaska family of PHYs supports 2.5GBaseT and 5GBaseT modes, as defined in the 802.3bz specification. Upon establishing a 2.5GBASET link, the PHY will reconfigure it's MII interface to 2500BASEX. At 5G, the PHY will reconfigure it's interface to 5GBASE-R, but this mode isn't supported by any MAC for now. This was tested with : - The 88X3310, which is on the MacchiatoBin - The 88E2010, an Alaska PHY that has no fiber interfaces, and is limited to 5G maximum speed.

2019-02-24net: phy: check PMAPMD link status only in genphy_c45_read_linkHeiner Kallweit
The current code reports a link as up if all devices (except a few blacklisted ones) report the link as up. This breaks Aquantia AQCS109 for lower speeds because on this PHY the PCS link status reflects a 10G link only. For Marvell there's a similar issue, therefore PHYXS device isn't checked. There may be more PHYs where depending on the mode the link status of only selected devices is relevant. For now it seems to be sufficient to check the link status of the PMAPMD device only. Leave the loop in the code to be prepared in case we have to add functionality to check more than one device, depending on the mode. Successfully tested on a board with an AQCS109.

2019-02-23net: phy: realtek: Dummy IRQ calls for RTL8366RBLinus Walleij
This fixes a regression introduced by commit 0d2e778e38e0ddffab4bb2b0e9ed2ad5165c4bf7 "net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt". This assumes that a PHY cannot trigger interrupt unless it has .config_intr() or .ack_interrupt() implemented. A later patch makes the code assume both need to be implemented for interrupts to be present. But this PHY (which is inside a DSA) will happily fire interrupts without either callback. Implement dummy callbacks for .config_intr() and .ack_interrupt() in the phy header to fix this. Tested on the RTL8366RB on D-Link DIR-685.

2019-02-23net: phy: marvell10g: Fix Multi-G advertisement to only advertise 10GMaxime Chevallier
Some Marvell Alaska PHYs support 2.5G, 5G and 10G BaseT links. Their default behaviour is to advertise all of these modes, but at the moment, only 10GBaseT is supported. To prevent link partners from establishing link at that speed, clear these modes upon configuring aneg parameters.

Use devm_hwmon_device_register_with_info() instead of devm_hwmon_device_register_with_groups() to register the hwmon device to simplify the code and make it easier to maintain. As part of this change, thermal device registration is moved into the hwmon core. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

KASAN has found use-after-free in fixed_mdio_bus_init, commit 0c692d07842a ("drivers/net/phy/mdio_bus.c: call put_device on device_register() failure") call put_device() while device_register() fails,give up the last reference to the device and allow mdiobus_release to be executed ,kfreeing the bus. However in most drives, mdiobus_free be called to free the bus while mdiobus_register fails. use-after-free occurs when access bus again, this patch revert it to let mdiobus_free free the bus.

2019-02-22net: phy: at803x: disable delay only for RGMII modeVinod Koul
Per "Documentation/devicetree/bindings/net/ethernet.txt" RGMII mode should not have delay in PHY whereas RGMII_ID and RGMII_RXID/RGMII_TXID can have delay in PHY. So disable the delay only for RGMII mode and enable for other modes. Also treat the default case as disabled delays.

The code waits up to 20 usec for the firmware response to complete once we've seen the valid response header in the buffer. It turns out that in some scenarios, this wait time is not long enough. Extend it to 150 usec and use usleep_range() instead of udelay().
