In this patch, consumers are allowed to set suspend voltage, and this actually just set the "uV" in constraint::regulator_state, when the regulator_suspend_late() was called by PM core through callback when the system is entering into suspend, the regulator device would act suspend activity then. And it assumes that if any consumer set suspend voltage, the regulator device should be enabled in the suspend state. And if the suspend voltage of a regulator device for all consumers was set zero, the regulator device would be off in the suspend state. This patch also provides a new function hook to regulator devices for resuming from suspend states.

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.
