Atm, the power well IDs are defined in separate platform specific enums, which isn't ideal for the following reasons: - the IDs are used by helpers like lookup_power_well() in a platform independent way - the always-on power well is used by multiple platforms and so needs now separate IDs, although these IDs refer to the same thing To make things more consistent use a single enum instead of the two separate ones, listing the IDs per platform (or set of very similar platforms like all GEN9/10). Replace the separate always-on power well IDs with a single ID. While at it also add a note clarifying the distinction between regular power wells that follow a common programming pattern and custom ones that are programmed in some other way. The IDs for regular power wells need to stay fixed, since they also define the request and state HW flag positions in their corresponding power well control register(s). v2: - Add comment about id to req,status bit mapping to the enum.

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.
