The CPUFREQ driver framework references each individual CPUs when getting and setting the speed. Tegra186 has 3 clusters of A57 CPUs and 1 cluster of Denver CPUs. Hence, the Tegra186 CPUFREQ driver need to know which cluster a given CPU belongs to. The logic in the Tegra186 driver can be greatly simplified by storing the cluster ID associated with each CPU in the tegra186_cpufreq_cpu structure. This allow us to completely remove the Tegra cluster info structure from the driver and simplifiy the code.

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.
