With new version of TMC ETR, there are differing set of features supported by the TMC. Add the capability of a given TMC ETR for making safer decisions at runtime. The device configuration register of the TMC (DEVID) lists some of the capabilities. So, we can detect some of them at probe. However, some of the features (or changes in behavior) are not advertised and we have to depend on the PID to infer the features. So we use a static description of the "unadvertised" capabilities attached to the PID. Combining both, the static and the dynamic capabilities, we maintain a bitmask of the available features which can be later checked to take appropriate actions.

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.
