PSGMII is a Qualcomm specific mode similar to QSGMII but it has 5 SGMII lines instead of 4 in QSGMII. This just adds the support for the PHY layer to be able to identify the mode for further use. It is required for the DSA driver. Signed-off-by: Robert Marko <robert.marko@sartura.hr>

Subject: [PATCH] net: phy: define PSGMII PHY interface mode
|
|
|
|
The PSGMII interface is similar to QSGMII. The main difference
|
|
is that the PSGMII interface combines five SGMII lines into a
|
|
single link while in QSGMII only four lines are combined.
|
|
|
|
Similarly to the QSGMII, this interface mode might also needs
|
|
special handling within the MAC driver.
|
|
|
|
Add definitions for the PHY layer to allow to express this type
|
|
of connection between the MAC and PHY.
