net: ftgmac100: fix potential NULL pointer access in ftgmac100_phy_disconnect

2025-08-05T23:00:53+00:00

After the call to phy_disconnect() netdev->phydev is reset to NULL. So fixed_phy_unregister() would be called with a NULL pointer as argument. Therefore cache the phy_device before this call.

net: ftgmac100: Add optional reset control for RMII mode on Aspeed SoCs

2025-07-11T01:13:52+00:00

On Aspeed SoCs, the internal MAC reset is insufficient to fully reset the RMII interface; only the SoC-level reset line can properly reset the RMII logic. This patch adds support for an optional "resets" property in the device tree, allowing the driver to assert and deassert the SoC reset line when operating in RMII mode. This ensures the MAC and RMII interface are correctly reset and initialized.

net: ftgmac100: select FIXED_PHY

2025-06-18T21:11:16+00:00

Depending on e.g. DT configuration this driver uses a fixed link. So we shouldn't rely on the user to enable FIXED_PHY, select it in Kconfig instead. We may end up with a non-functional driver otherwise.

net: phy: fixed_phy: remove irq argument from fixed_phy_register

2025-05-21T01:17:43+00:00

All callers pass PHY_POLL, therefore remove irq argument from fixed_phy_register(). Note: I keep the irq argument in fixed_phy_add_gpiod() for now, for the case that somebody may want to use a GPIO interrupt in the future, by e.g. adding a call to fwnode_irq_get() to fixed_phy_get_gpiod().

net: ftgmac100: refactor getting phy device handle

2024-10-29T22:41:16+00:00

Consolidate the handling of dedicated PHY and fixed-link phy by taking advantage of logic in of_phy_get_and_connect() which handles both of these cases, rather than open coding the same logic in ftgmac100_probe().

net: ftgmac100: fixed not check status from fixed phy

2024-10-10T00:56:55+00:00

Add error handling from calling fixed_phy_register. It may return some error, therefore, need to check the status. And fixed_phy_register needs to bind a device node for mdio. Add the mac device node for fixed_phy_register function. This is a reference to this function, of_phy_register_fixed_link().

net: ethernet: Switch back to struct platform_driver::remove()

2024-10-04T23:39:56+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/net/ethernet to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
