Like other Qualcomm SoCs, sm8150 exposes CPU and cluster idle states through PSCI. Define the idle states to save power when the CPU is not in active use. These idle states, latency, and residency values match the downstream 4.14 kernel from Qualcomm as of LA.UM.8.1.r1-15600-sm8150.0. It's worth noting that the CPU has an additional C3 power collapse idle state between WFI and rail power collapse (with PSCI mode 0x40000003), but it is not officially used in downstream kernels due to "thermal throttling issues."

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.
