As of today, the only cool and legal way to get ARM64 SMP going is
via PSCI (or spin tables). Sadly, not all chip and device vendors were
considerate of this in the early days of arm64. Qualcomm, for example
reused their tried-and-true spin-up method from MSM8974 and their Krait/
arm32 Cortex designs.
MSM8916 supports SMP with its arm32 dt overlay, as probably could 8939.
But the arm64 DT should not define non-PSCI SMP or CPUidle stuff.
Drop the qcom,idle-state-spc compatible (associated with Qualcomm-specific
CPUIdle) to make the dt checker happy:
apq8039-t2.dtb: idle-states: cpu-sleep-0:compatible:
['qcom,idle-state-spc', 'arm,idle-state'] is too long

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
