[PATCH] arm64: dts: qcom: pm8005: Add pmic cooling maps

[Dipa Ramesh Mantre]

Add CPU mitigation cooling maps for pm8005 PMIC die temperature.
Throttle LITTLE (cpu0) and big (cpu3) clusters at 105°C and 125°C
trip points.

You're making changes to a shared file with the intent of altering the
behavior of a specific platform. Furthermore, you don't explain how
the CPU frequency correlates to the temperature of the PMIC die, leaving
that to the imagination of the reader.

Thanks for the comment, will fix this and update the reasoning in the 
commit.

https://docs.kernel.org/process/submitting-patches.html#describe-your-changes:

Describe your problem. Whether your patch is a one-line bug fix or 5000
lines of a new feature, there must be an underlying problem that
motivated you to do this work. Convince the reviewer that there is a
problem worth fixing and that it makes sense for them to read past the
first paragraph.

I'm guessing since you depend on some feature branch called "adc
support" this patch can't be applied. Work with your peers to land your
dependencies and then build and TEST on the clean upstream branch.

Thanks,
