Backup area is now switched to VDDIN33 at boot (with the help of bootloader). When switching to backup mode we need to switch backup area to VBAT as all the other power sources are cut off. The resuming from backup mode is done with the help of bootloader, so there is no need to do something particular in Linux to restore backup area power source.

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.
