The initial idea of creating the cpufreq-dt-platdev.c file was to keep a list of platforms that use the "operating-points" (V1) bindings and create cpufreq device for them only, as we weren't sure which platforms would want the device to get created automatically as some had their own cpufreq drivers as well, or wanted to initialize cpufreq after doing some stuff from platform code. But that wasn't the case with platforms using "operating-points-v2" property. We wanted the device to get created automatically without the need of adding them to the whitelist. Though, we will still have some exceptions where we don't want to create the device automatically. Rename the earlier platform list as *whitelist* and create a new *blacklist* as well. The cpufreq-dt device will get created if: - The platform is there in the whitelist OR - The platform has "operating-points-v2" property in CPU0's DT node and isn't part of the blacklist .

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
