Depending directly on the bus driver's global cci_ctrl_base variable is a little unpleasant, and exporting it to allow the PMU driver to be modular would be even more so. Let's make things a little better abstracted by adding the control register block to the cci_pmu instance data alongside the PMU register block, and communicating the mapped address from the bus driver via platform data. It's not practical to try the same thing for the bus driver itself, given that the globals are entangled with the hairy assembly code for port control, so we leave them be there. It would however be prudent to move them to the __ro_after_init section in passing, since the addresses really should never be changing once set.

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.
