QCA808x does not currently fill in the possible_interfaces. This leads to Phylink not being aware that it supports 2500Base-X as well so in cases where it is connected to a DSA switch like MV88E6393 it will limit that port to phy-mode set in the DTS. That means that if SGMII is used you are limited to 1G only while if 2500Base-X was set you are limited to 2.5G only. Populating the possible_interfaces fixes this, so lets backport the patches from kernel 6.9. This also includes a backport of the Phylink PHY validation series from kernel 6.8 that allows the use of possible_interfaces.

Subject: [PATCH 2/2] net: phy: qcom: qca808x: fill in possible_interfaces
|
|
|
|
Currently QCA808x driver does not fill the possible_interfaces.
|
|
2.5G QCA808x support SGMII and 2500Base-X while 1G model only supports
|
|
SGMII, so fill the possible_interfaces accordingly.
