net: phy: Support overriding Auto Negotiation timeout with env variable

2025-08-01T08:42:22Z

The Auto Negotiation procedure between two Ethernet PHYs consists of determining the best commonly supported parameters among Speed, Duplex Mode and Flow Control. The time taken for this procedure is not only dependent on the local PHY used, but also on the link-partner PHY. While a timeout can be specified in the form of a "CONFIG" on the basis of the local PHY present on the device, since the timeout also depends on the link-partner PHY, it might be necessary to modify the timeout. To avoid rebuilding the bootloader for a given device, just because it may be connected to various link-partner PHYs, each with a different timeout, introduce an environment variable named "phy_aneg_timeout" and override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

net: phy: Do not do CL22 phy reset before ethernet phy driver probe

2025-05-23T17:33:37Z

Remove unnecessary CL22 phy reset before ethernet phy driver probe. Lots of ethernet phys requires driver to load firmware. Before that, CL22 phy reset may lead to malfunction. Signed-off-by: SkyLake.Huang

net: phy: Replace PHY_ANEG_TIMEOUT with Kconfig symbol

2024-06-13T22:27:07Z

Switch PHY_ANEG_TIMEOUT to CONFIG_PHY_ANEG_TIMEOUT Kconfig symbol. This removes one more configuration headers option finalizes its Kconfig symbol conversion. No functional change expected. Signed-off-by: Marek Vasut

Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"

2024-05-20T19:35:03Z

As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

net: Remove and add needed includes

2024-05-07T14:00:55Z

Remove from this driver directory and when needed add missing include files directly. Signed-off-by: Tom Rini

net: phy: Factor out PHY GPIO reset code

2024-03-26T23:58:26Z

Pull the PHY GPIO reset code into separate function, since this is and will be reused multiple times. Set up default reset assert and deassert timing to generous 20ms and 1ms for maximum compatibility in case those DT properties are missing. Reviewed-by: Ramon Fried Signed-off-by: Marek Vasut

net: phy: the NC-SI phy device do not require mdio bus

2024-03-26T23:58:26Z

As with fixed-link phy device, the NC-SI phy devive does not require an mdio bus. So, a condition is added to check the NC-SI phy id to avoid accessing the bus pointer that is NULL. Signed-off-by: Jacky Chou

net: phy: Fix signed shift overflow

2024-03-26T23:58:26Z

Booting R-Car Gen3 arm64 U-Boot with CONFIG_UBSAN=y resulted in: ===================================================================== UBSAN: Undefined behaviour in drivers/net/phy/phy.c:728:19 left shift of 1 by 31 places cannot be represented in type 'int' ===================================================================== Fix it by appending the UL suffix to the numeric literal. While at it, convert the type of "addr" variable from signed to unsigned, to protect against shifting the numeric literal by a negative value (which would lead to yet another undefined behavior). Fixes: 1adb406b0141 ("phy: add phy_find_by_mask/phy_connect_dev") Signed-off-by: Eugeniu Rosca * Using U-suffix for integer is sufficient. * ffs() of non-zero value cannot be 0. But addr being unsigned is * preferable. Signed-off-by: Heinrich Schuchardt

net: phy: xilinx-gmii2rgmii: Removed hardcoded phy address 0 for bridge

2023-09-21T11:20:11Z

Current code expects bridge phy address at 0 which is not correct expectation because bridge phy address is configurable. That's why update the code to read reg property to figure it out where bridge is and use it in phy creation code.
