Using getnstimeofday()/timespec_to_ns() causes an overflow on 32-bit architectures in 2038, and may suffer from time jumps due to settimeofday() or leap seconds. I don't see a reason why this needs to be UTC, so either monotonic or boot time would be better here. Assuming that the fw time keeps running during suspend, boottime is better than monotonic, and ktime_get_boot_ns() will also save the additional conversion to nanoseconds.

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.
