This series adds support for am437x RTC-only mode in suspend. In the RTC-only mode suspend, everything is shut down except the RTC. This makes the power consumption very low for suspend mode. To support RTC-only mode, we need to export omap_rtc_power_off_program() from the rtc driver and improve PM code to save and restore the wkup domain context. As RTC-only mode depends on the device being wired properly for things like memory, we need to also check for the machine type before we allow it. We also need to run DDR3 hardware leveling on resume. Note that there is a trivial merge conflict between the RTC branch and these changes where the RTC branch makes tm2bcd() a void function and the error handling parts can be just dropped. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAlywwLIRHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXOBhg/+NRYTBaO4pmFKlTMKs+bgdpftHf6wPSID kUy62YiKhMMgbe6J+Ts/Hk2kCibuOfFmQ0axGFdHzMhpwTGThsWFiwaVr7OKF6ZE DwOlJ1ZwM2OXcdf8wVupRL/54Tg1Wjc6y/T63Q5K+IqKz7gjdf6n7CXdYn22qTmp 4WK81dW1fx+9QNBbGBmMXEbNRlEImxeZRnWF1zJvydOCxO0jRbgnlGgpZJr36TeL Jj+HN+4fD6WmaQ3Slbgcr0jbAowjjTuyUfFwzEBe9G2KlxRyrxDd4ryY78tNxcIe L+yNMm7RGHD1Mb0+tdmpXESuj+O4hsuXglnK5vl19yc95nbwbTeRu0sv+WBEAal4 mY7xTMzT08rLT7fDXuJ+5vZNbR1TLGIekmNnj5BvV8LyZ9ypXToOlOCtFonQxULu HFsiDkOOdKQhkuzw+V8EBksMXdD5crTVxyHY95hguvWTBUMTJjBo0Bq/9EmhKx0m HOglctIivV1/GFg/82QKatjXLLeuXtFqUJa7lc6GIkVteAvEhrbg2DQ8QhnZ8Zg+ ghx0kKsA+KXvOItI6JrMjk/GQuwXTcIytkUhfTVuVlN+gV2PbGFCbohJOatwtXkp 0+VQ0H6AN04FJPqgLDR1njvks6Ll503gbnqodDNL/xgaN+Pjw5zTabkM/hdIyCNV KS6XhdlYvtQ= =yNbG -----END PGP SIGNATURE----- Merge tag 'omap-for-v5.2/am4-pm-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers PM changes for am335x and am437x This series adds support for am437x RTC-only mode in suspend.

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.
