Configure SerDes (port 4) RX and TX polarities using the newly introduced generic properties. The polarities are described at the port level which equals the polarities of the external pins of the chip. Note that the RX lane is inverted internally and the vendor driver simply always sets bit GSW1XX_SGMII_PHY_RX0_CFG2_INVERT unconditionally to end up with the correct (ie. as documented in datasheets) polarity at the external pins. In this sense, PHY_POLARITY_NORMAL denotes normal polarity for pins as documented for the MRQFN 105-pin package (GSW120, GSW125, GSW140, GSW141 and GSW145 all use the same package and have identical pin layouts except for TP port 2 and 3 being N/C on GSW12x): pin B18 (TX0_P) positive signal of the differential SGMII data output pair pin B19 (TX0_M) negative signal of the differential SGMII data output pair pin B20 (RX0_P) positive signal of the differential SGMII data input pair pin B21 (RX0_M) negative signal of the differential SGMII data input pair Signed-off-by: Daniel Golle <daniel@makrotopia.org> Link: https://patch.msgid.link/8bf79b3476e23673fceffbe2bc9d6abc13d132e5.1769916962.git.daniel@makrotopia.org Reviewed-by: Vladimir Oltean <olteanv@gmail.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
