2025-05-27net: phy: mediatek: Add Airoha AN7583 PHY supportChristian Marangi
Add Airoha AN7583 PHY support based on Airoha AN7581 with the small difference that BMCR_PDOWN is enabled by default and needs to be cleared to make the internal PHY correctly work.

2025-05-20net: phy: mediatek: add driver for built-in 2.5G ethernet PHY on MT7988Sky Huang
Add support for internal 2.5Gphy on MT7988. This driver will load necessary firmware and add appropriate time delay to make sure that firmware works stably. The firmware loading procedure takes about 11ms in this driver.

2025-05-16net: phy: mediatek: do not require syscon compatible for pio propertyFrank Wunderlich
Current implementation requires syscon compatible for pio property which is used for driving the switch leds on mt7988. Replace syscon_regmap_lookup_by_phandle with of_parse_phandle and device_node_to_regmap to get the regmap already assigned by pinctrl driver.

2025-04-11net: phy: mediatek: add Airoha PHY ID to SoC driverChristian Marangi
Airoha AN7581 SoC ship with a Switch based on the MT753x Switch embedded in other SoC like the MT7581 and the MT7988. Similar to these they require configuring some pin to enable LED PHYs. Add support for the PHY ID for the Airoha embedded Switch and define a simple probe function to toggle these pins. Also fill the LED functions and add dedicated function to define LED polarity.

2025-04-11net: phy: mediatek: permit to compile test GE SOC PHY driverChristian Marangi
When commit 462a3daad679 ("net: phy: mediatek: fix compile-test dependencies") fixed the dependency, it should have also introduced an or on COMPILE_TEST to permit this driver to be compile-tested even if NVMEM_MTK_EFUSE wasn't selected. The driver makes use of NVMEM API that are always compiled (return error) so the driver can actually be compiled even without that config. Fix and simplify the dependency condition of this kernel config.

2025-02-17net: phy: mediatek: Add token ring access helper functions in mtk-phy-libSky Huang
This patch adds TR(token ring) manipulations and adds correct macro names for those magic numbers. TR is a way to access proprietary registers on page 52b5. Use these helper functions so we can see which fields we're going to modify/set/clear. TR functions with __* prefix mean that the operations inside aren't wrapped by page select/restore functions. This patch doesn't really change registers' settings but just enhances readability and maintainability.
