If an application set a tight sampling frequency, given the interrupt use is a wakeup source, suspend will not happen: the kernel will receive a wake up interrupt and will cancel the suspend process. Given cros_ec sensors type is non wake up, this patch adds prepare and complete callbacks to set 1s sampling period just before suspend. This ensures the sensor hub will not be a source of interrupt during the suspend process.

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.
