The registers for the bt-bmc device live under the Aspeed LPC controller. Devicetree bindings have recently been introduced for the LPC controller where the "host" portion of the LPC register space is described as a syscon device. Future devicetrees describing the bt-bmc device should nest its node under the appropriate "simple-mfd", "syscon" compatible node. This change allows the bt-bmc driver to function with both syscon and non-syscon- based devicetree descriptions by always using a regmap for register access, either retrieved from the parent syscon device or instantiated if none exists.

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.
