Many devices may want to request a bunch of resets and control them. So it's better to manage them as an array. Add APIs to _get() an array of reset_control, reusing the _assert(), _deassert(), and _reset() APIs for single reset controls. Since reset controls already may control multiple reset lines with a single hardware bit, from the user perspective, reset control arrays are not at all different from single reset controls. Note that these APIs don't guarantee that the reset lines managed in the array are handled in any particular order.

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.
