-Subject: ARM: dts: am335x-boneblack: disable RTC-only sleep to avoid hardware damage
-
-From: Matthijs van Duin <matthijsvanduin@gmail.com>
-
-commit 7a6cb0abe1aa63334f3ded6d2b6c8eca80e72302 upstream.
-
-Avoid entering "RTC-only mode" at poweroff. It is unsupported by most
-versions of BeagleBone, and risks hardware damage.
-
-The damaging configuration is having system-power-controller
-without ti,pmic-shutdown-controller.
