As per 8.2.6 Setting and reading the time in RTC mode, first stop the clok, then reset it before setting the date and time registers. Finally, start the clock. This uses register address wrap around from 0x2f to 0x00 for efficiency. This allows to set the clock with a millisecond accuracy (drift is not corrected in this example): RTC System 1325388767 1325388767.000029180 1325388768 1325388768.000018362 1325388769 1325388769.000006544 1325388770 1325388769.999992725 1325388771 1325388770.999974544 Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
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.
