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
So the one mentioned in the rt-rk article and a load of CVEs is _not_
QCA8084 but is APQ8084. Sounds like a lot of people are getting stuff
wrong - which is hardly surprising as there are people that seem to
_enjoy_ getting the technical details wrong. I haven't worked out if
it's intentional malace, or they're just fundamentally lazy individuals
who just like to screw with other people.
Sigh.
Hoping to give some clarification with the naming.
- APQ8084 ("Application" SoC for 8084 family)
- IPQ8084 ("Internet" SoC version of APQ8084)
- QCA8084 (Integrated PHYs in the IPQ8084 SoC)
I guess? >
Considering QCA8084 is only in in IPQ8084 SoC, the confusion with
referring to it is in the fact that it's all the same thing, and
everything related to APQ is also related to IPQ since they are the same
SoC with minor difference (different DSP, presence of NSS cores)
I can totally see sencente like "The IPQ8084 PHYs..." referencing the
QCA8084 PHY.
(Just to put how the naming is confusing there are PMIC with the
same exact naming)
There should be NO IPQ8084.
Yes, APQ8084 is the application SoC.
QCA8084 is the pure PHY chip which has quad-phy.
The prefix QCA is the Ethernet device, like qca8081(PHY chip), qca8386(
switch chip) and qca8084(PHY chip).
The prefix IPQ is the internet processor SoC, like ipq5332.
