Currently, SSDK is creating a fake SFP PHY which has no OF node populated, thus making it impossible to pass it to NSS-DP so port can actually work. We eliminated QCA-s connecting of the PHY by manually creating a string and then matching by name and instead only support passing the PHY as phandle via phy-handle. So, lets just use the switch port node to which the SFP is connected to anyway and set it as the PHY device OF node so we can pass it to NSS-DP.

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.
