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. + +Signed-off-by: Gabor Juhos <j4g8y7@gmail.com> +--- + Documentation/devicetree/bindings/net/ethernet-controller.yaml | 1 + + drivers/net/phy/phylink.c | 1 + + include/linux/phy.h | 3 +++ + 3 files changed, 5 insertions(+) + +--- a/Documentation/devicetree/bindings/net/ethernet-controller.yaml ++++ b/Documentation/devicetree/bindings/net/ethernet-controller.yaml +@@ -64,6 +64,7 @@ properties: + - mii + - gmii + - sgmii ++ - psgmii + - qsgmii + - tbi + - rev-mii +--- a/drivers/net/phy/phylink.c ++++ b/drivers/net/phy/phylink.c +@@ -293,6 +293,7 @@ static int phylink_parse_mode(struct phy + + switch (pl->link_config.interface) { + case PHY_INTERFACE_MODE_SGMII: ++ case PHY_INTERFACE_MODE_PSGMII: + case PHY_INTERFACE_MODE_QSGMII: + phylink_set(pl->supported, 10baseT_Half); + phylink_set(pl->supported, 10baseT_Full); +--- a/include/linux/phy.h ++++ b/include/linux/phy.h +@@ -138,6 +138,7 @@ typedef enum { + PHY_INTERFACE_MODE_XGMII, + PHY_INTERFACE_MODE_XLGMII, + PHY_INTERFACE_MODE_MOCA, ++ PHY_INTERFACE_MODE_PSGMII, + PHY_INTERFACE_MODE_QSGMII, + PHY_INTERFACE_MODE_TRGMII, + PHY_INTERFACE_MODE_100BASEX, +@@ -209,6 +210,8 @@ static inline const char *phy_modes(phy_ + return "xlgmii"; + case PHY_INTERFACE_MODE_MOCA: + return "moca"; ++ case PHY_INTERFACE_MODE_PSGMII: ++ return "psgmii"; + case PHY_INTERFACE_MODE_QSGMII: + return "qsgmii"; + case PHY_INTERFACE_MODE_TRGMII: |
