phy: add hwtstamp_get callback to phy drivers

2025-11-27T00:56:33+00:00

PHY devices had lack of hwtstamp_get callback even though most of them are tracking configuration info. Introduce new call back to mii_timestamper.

phy: rename hwtstamp callback to hwtstamp_set

2025-11-27T00:56:33+00:00

PHY devices has hwtstamp callback which actually performs set operation. Rename it to better reflect the action.

net: Add struct kernel_ethtool_ts_info

2024-07-15T15:02:26+00:00

In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

net: Convert PHYs hwtstamp callback to use kernel_hwtstamp_config

2023-11-18T14:52:56+00:00

The PHYs hwtstamp callback are still getting the timestamp config from ifreq and using copy_from/to_user. Get rid of these functions by using timestamp configuration in parameter. This also allow to move on to kernel_hwtstamp_config and be similar to net devices using the new ndo_hwstamp_get/set. This adds the possibility to manipulate the timestamp configuration from the kernel which was not possible with the copy_from/to_user.

net: Add a layer for non-PHY MII time stamping drivers.

2019-12-26T03:51:33+00:00

While PHY time stamping drivers can simply attach their interface directly to the PHY instance, stand alone drivers require support in order to manage their services. Non-PHY MII time stamping drivers have a control interface over another bus like I2C, SPI, UART, or via a memory mapped peripheral. The controller device will be associated with one or more time stamping channels, each of which sits snoops in on a MII bus. This patch provides a glue layer that will enable time stamping channels to find their controlling device. Signed-off-by: Richard Cochran Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: Introduce a new MII time stamping interface.

2019-12-26T03:51:33+00:00

Currently the stack supports time stamping in PHY devices. However, there are newer, non-PHY devices that can snoop an MII bus and provide time stamps. In order to support such devices, this patch introduces a new interface to be used by both PHY and non-PHY devices. In addition, the one and only user of the old PHY time stamping API is converted to the new interface. Signed-off-by: Richard Cochran Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller
