The Hi3660 SoC comes with the sp804 timer in addition to the architecture timers. These ones are shutdown when reaching a deep idle states and a backup timer is needed. The sp804 belongs to another power domain and can fulfill the purpose of replacing temporarily an architecture timer when the CPU is idle. Describe it in the device tree, so it can be enabled at boot time.

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.
