[PATCH v2 08/11] arm64: dts: qcom: Add SM7325 device tree
Posted by Danila Tikhonov 1 year, 6 months ago 
From: Eugene Lepshy <fekz115@gmail.com>

The Snapdragon 778G (SM7325) / 778G+ (SM7325-AE) / 782G (SM7325-AF)
is software-wise very similar to the Snapdragon 7c+ Gen 3 (SC7280).

It uses the Kryo670.

This is a meaningless marketing name. As you mentioned in your
reply, cpu0-3 and cpu4-7 are wholly different (maybe cpu7 even
has a different MIDR part num?), we should do something about it :/

Please post the output of `dmesg | grep "Booted secondary processor"`

No PMU? Because PMUs are also a per CPU model compatible string.

I fixed most QCom platforms recently.

Sorry for my long reply and thank you for your feedback.

You are absolutely right. But at the moment I can't confirm that the
sc7280 doesn't use cortex a55 and a78 either. I would fix that in the
sc7280 DTS right away if I could confirm it. I am almost certain that
the qcm6490 uses cortex a55 and a78 just like the sm7325 (and I
hope Luca Weiss can confirm that too)

If anyone with a sc7280 can read /proc/cpuinfo I would be very grateful.

Best wishes,
Danila
