phy: mscc: Fix when PTP clock is register and unregister

2025-08-27T00:10:51Z

It looks like that every time when the interface was set down and up the driver was creating a new ptp clock. On top of this the function ptp_clock_unregister was never called. Therefore fix this by calling ptp_clock_register and initialize the mii_ts struct inside the probe function and call ptp_clock_unregister when driver is removed.

phy: mscc: Fix timestamping for vsc8584

2025-08-20T00:52:02Z

There was a problem when we received frames and the frames were timestamped. The driver is configured to store the nanosecond part of the timestmap in the ptp reserved bits and it would take the second part by reading the LTC. The problem is that when reading the LTC we are in atomic context and to read the second part will go over mdio bus which might sleep, so we get an error. The fix consists in actually put all the frames in a queue and start the aux work and in that work to read the LTC and then calculate the full received time.

net: phy: mscc: report and configure in-band auto-negotiation for SGMII/QSGMII

2025-08-15T00:42:32Z

The following Vitesse/Microsemi/Microchip PHYs, among those supported by this driver, have the host interface configurable as SGMII or QSGMII: - VSC8504 - VSC8514 - VSC8552 - VSC8562 - VSC8572 - VSC8574 - VSC8575 - VSC8582 - VSC8584 All these PHYs are documented to have bit 7 of "MAC SerDes PCS Control" as "MAC SerDes ANEG enable". Out of these, I could test the VSC8514 quad PHY in QSGMII. This works both with the in-band autoneg on and off, on the NXP LS1028A-RDB and T1040-RDB boards. Notably, the bit is sticky (survives soft resets), so giving Linux the tools to read and modify this settings makes it robust to changes made to it by previous boot layers (U-Boot).

net: phy: extend PHY package API to support multiple global address

2023-12-17T20:10:07Z

Current API for PHY package are limited to single address to configure global settings for the PHY package. It was found that some PHY package (for example the qca807x, a PHY package that is shipped with a bundle of 5 PHY) requires multiple PHY address to configure global settings. An example scenario is a PHY that have a dedicated PHY for PSGMII/serdes calibrarion and have a specific PHY in the package where the global PHY mode is set and affects every other PHY in the package. Change the API in the following way: - Change phy_package_join() to take the base addr of the PHY package instead of the global PHY addr. - Make __/phy_package_write/read() require an additional arg that select what global PHY address to use by passing the offset from the base addr passed on phy_package_join(). Each user of this API is updated to follow this new implementation following a pattern where an enum is defined to declare the offset of the addr. We also drop the check if shared is defined as any user of the phy_package_read/write is expected to use phy_package_join first. Misuse of this will correctly trigger a kernel panic for NULL pointer exception. Signed-off-by: Christian Marangi Signed-off-by: David S. Miller

phy: mscc: Use PHY_ID_MATCH_VENDOR to minimize PHY ID table

2023-06-01T05:33:45Z

All the PHY devices variants specified have the same mask and hence can be simplified to one vendor look up for 0x00070400. Any individual config can be identified by PHY_ID_MATCH_EXACT in the respective structure. Signed-off-by: Harini Katakam Reviewed-by: Andrew Lunn Signed-off-by: Jakub Kicinski

net: phy: mscc: enable VSC8501/2 RGMII RX clock

2023-05-25T05:14:23Z

By default the VSC8501 and VSC8502 RGMII/GMII/MII RX_CLK output is disabled. To allow packet forwarding towards the MAC it needs to be enabled. For other PHYs supported by this driver the clock output is enabled by default.

net: phy: mscc: coma mode disabled for VSC8514

2021-02-16T22:06:19Z

The 'coma mode' (configurable through sw or hw) provides an optional feature that may be used to control when the PHYs become active. The typical usage is to synchronize the link-up time across all PHY instances. This patch releases coma mode if not done by hardware, otherwise the phys will not link-up.
