Ah, that is new information, and has a big effect on the design.
This QCA8084 that's being proposed in these patches is not a PHY in
itself, but is a SoC. I came across this:
https://www.rt-rk.com/android-tv-solution-tv-in-smartphone-pantsstb-based-on-qualcomm-soc-design/
The chip mentioned in the link you mentioned is SoC, which is not the
chip that the qca8084 driver work for.
So there's two chips called QCA8084 both produced by Qualcomm? I find
that hard to believe.
The SoC mentioned in the link you provided is the APQ8084 that is
introduced in the link below:
https://www.qualcomm.com/products/mobile/snapdragon/smartphones/snapdragon-8-series-mobile-platforms/snapdragon-processors-805
https://hwbot.org/hardware/processor/snapdragon_805_apq8084_pro__(8084_fusion_4.5)_2700mhz/
The driver here is for qca8084, which has the different prefix,
and qca8084 is the Ethernet CHIP like qca8081, but qca8084 is
multiple ports(quad-phy).
