For historical reasons, rate detection when probing via DT is somewhat convoluted. We tried to package this up in arch_timer_detect_rate(), but with the addition of ACPI worse, and gets in the way of stringent rate checking when ACPI is used. This patch makes arch_timer_detect_rate() specific to DT, ripping out ACPI logic. In preparation for rework of the MMIO timer probing, the reading of the relevant CNTFRQ register is factored out to callers. The function is then renamed to arch_timer_of_configure_rate(), which better represents its new place in the world. Comments are added in the DT and ACPI probe paths to explain this.

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.
