[ Upstream commit 3c25a860d17b7378822f35d8c9141db9507e3beb ] Commit fcb26ec5b18d ("broadcom: move all PHY_ID's to header") updated broadcom_tbl to use PHY_IDs, but incorrectly replaced 0x0143bca0 with PHY_ID_BCM5482 (making a duplicate entry, and completely omitting the original).

2015-07-10net: phy: fix phy link up when limiting speed via device treeMugunthan V N
[ Upstream commit eb686231fce3770299760f24fdcf5ad041f44153 ] When limiting phy link speed using "max-speed" to 100mbps or less on a giga bit phy, phy never completes auto negotiation and phy state machine is held in PHY_AN. Fixing this issue by comparing the giga bit advertise though phydev->supported doesn't have it but phy has BMSR_ESTATEN set. So that auto negotiation is restarted as old and new advertise are different and link comes up fine.

[ Upstream commit 397a253af5031de4a4612210055935309af4472c ] Currently, the calibration function that corrects the initial offsets among multiple devices only works the first time. If the function is called more than once, the calibration fails and bogus offsets will be programmed into the devices. In a well hidden spot, the device documentation tells that trigger indexes 0 and 1 are special in allowing the TRIG_IF_LATE flag to actually work. This patch fixes the issue by using one of the special triggers during the recalibration method. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

[ Upstream commit 7e14069651591c81046ffaec13c3dac8cb70f5fb ] RGMII interfaces come in multiple flavors: RGMII with transmit or receive internal delay, no delays at all, or delays in both direction. This change extends the initial check for PHY_INTERFACE_MODE_RGMII to cover all of these variants since EEE should be allowed for any of these modes, since it is a property of the RGMII, hence Gigabit PHY capability more than the RGMII electrical interface and its delays.

[ Upstream commit 54da5a8be3c1e924c35480eb44c6e9b275f6444e ] phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex) to find a valid entry in the settings array for the given speed and duplex value. For full duplex 1000baseT, this will return the first matching entry, which is the entry for 1000baseKX_Full.

2014-08-14net: phy: re-apply PHY fixups during phy_register_deviceFlorian Fainelli
[ Upstream commit d92f5dec6325079c550889883af51db1b77d5623 ] Commit 87aa9f9c61ad ("net: phy: consolidate PHY reset in phy_init_hw()") moved the call to phy_scan_fixups() in phy_init_hw() after a software reset is performed. By the time phy_init_hw() is called in phy_device_register(), no driver has been bound to this PHY yet, so all the checks in phy_init_hw() against the PHY driver and the PHY driver's config_init function will return 0. We will therefore never call phy_scan_fixups() as we should. Fix this by calling phy_scan_fixups() and check for its return value to restore the intended functionality. This broke PHY drivers which do register an early PHY fixup callback to intercept the PHY probing and do things like changing the 32-bits unique PHY identifier when a pseudo-PHY address has been used, as well as board-specific PHY fixups that need to be applied during driver probe time.

2014-02-04net: phy: ensure Gigabit features are masked off if requestedFlorian Fainelli
When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet MAC, the driver will restrict the phydev->supported modes to mask off Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features set by default in MII_CTRL1000, it will keep advertising these feature, so by the time we call genphy_config_advert(), the condition on phydev->supported having the Gigabit features on is false, and we do not update MII_CTRL1000 with updated values, and we keep advertising Gigabit features, eventually configuring the PHY for Gigabit whilst the Ethernet MAC does not support that. This patches fixes the problem by ensuring that the Gigabit feature bits are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit PHY, and then, if Gigabit features are supported, setting those and updating MII_CTRL1000 accordingly.

2013-12-17net: phy: suspend phydev when going to HALTEDSebastian Hesselbarth
When phydev is going to HALTED state, we can try to suspend it to safe more power. phy_suspend helper will check if PHY can be suspended, so just call it when entering HALTED state.

2013-12-11micrel: add support for KSZ8041RNLISergei Shtylyov
Renesas R-Car development boards use KSZ8041RNLI PHY which for some reason has ID of 0x00221537 that is not documented for KSZ8041-family PHYs and does not match the documented ID of 0x0022151x (where 'x' is the revision). We have to add the new #define PHY_ID_* and new ksphy_driver[] entry, almost the same as KSZ8041 one, differing only in the 'phy_id' and 'name' fields.

The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-12-09net: phy: consolidate PHY reset in phy_init_hw()Florian Fainelli
There are quite a lot of drivers touching a PHY device MII_BMCR register to reset the PHY without taking care of: 1) ensuring that BMCR_RESET is cleared after a given timeout 2) the PHY state machine resuming to the proper state and re-applying potentially changed settings such as auto-negotiation Introduce phy_poll_reset() which will take care of polling the MII_BMCR for the BMCR_RESET bit to be cleared after a given timeout or return a timeout error code. In order to make sure the PHY is in a correct state, phy_init_hw() first issues a software reset through MII_BMCR and then applies any fixups.
