Atomic transfers are required to properly power off a machine through an I2C controlled PMIC, such as the Actions Semi ATC260x series. System shutdown may happen with interrupts being disabled and, as a consequence, the kernel may hang if the driver does not support atomic transfers. This functionality is essentially implemented by polling the FIFO Status register until either Command Execute Completed or NACK Error bits are set.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
