This driver has a get_temp function used by the thermal framework that uses pm functions. However, the driver isn't registered in pm before it is registered in thermal framework, resulting in the pm_resume not being called and thus the IP not enabled. When the IP is disabled, the raw temp value is always 0. With the devices currently supported, it isn't a problem since with their respective formula, they return a really cold SoC temperature which isn't a problem for the thermal framework. But for future SoC that have a different formula, it could return a critically hot temperature, forcing the thermal framework to shutdown the board.

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.
