+Subject: [PATCH] qca-ssdk: support selecting PCS channel for PORT3 on IPQ6018
+
+When QCA8072 is used in PSGMII mode with IPQ6018, PCS used for second
+PHY port would overlap with one used by SGMII+ port. SoC has register
+to select different PCS in such case.
+
+Original code used PHY_ID for this decision, which also had other
+issues, but is no longer viable since we moved to upstream QCA807x
+driver.
+
+Introduce DT property port3_pcs_channel to allow describing this in DT.
+Default value is <2>, and for some QCA8072 designs <4> would be needed.
