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.
|
