During RTC-only suspend, power is lost to the wkup domain, so we need to save and restore the state of that domain. We also need to store some information within the RTC registers so that u-boot can do the right thing at powerup. The state is entered by getting the RTC to bring the pmic_power_en line low which will instruct the PMIC to disable the appropriate power rails after putting DDR into self-refresh mode. To bring pmic_power_en low, we need to get an ALARM2 event. Since we are running from SRAM at that point, it means calculating what the next second is (via ASM) and programming that into the RTC. This patch also adds support for wake up source detection. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> |

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.
