[PATCH net-next v2 0/2] net: phy: motorcomm: Add cable test support for internal YT861x PHYs

From: David Yang

Date: Tue Oct 06 2026 - 16:24:10 EST


The YT921x switches integrate GbE PHYs of the YT861x family (PHY ID
0x01e04281) on the switch-internal MDIO bus exposed by the yt921x DSA
driver. Add a driver entry and TDR cable test support.

v1: https://lore.kernel.org/r/20261004184246.1260426-1-mmyangfl@xxxxxxxxx
- split into a driver entry patch and a cable test patch
- update comments and kconfig
- add yt861x_config_init() and apply the auto sleep setting, restore auto
sleep when starting the TDR test fails
- use separate variables for the TDR status
