In the ULP1 mode, in order to achieve the lowest power consumption with the system in retention mode and be able to resume on the wake up events, all the clocks are shut off, inclusive the embedded 12MHz RC oscillator, and the number of wake up sources is limited as well. When the wake up event is asserted, the embedded 12MHz RC oscillator restarts automatically. The ULP1 (Ultra Low-power mode 1) is introduced by SAMA5D2. The previous size of pm_suspend.o was 2148 bytes. With the addition of ULP1 mode the new size of pm_suspend.o raised at 2456 bytes.

README
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.
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.
