   * Configure pmic to enter OFF-state instead of SLEEP-state ("RTC-only

   * mode") at poweroff.  Most BeagleBone versions do not support RTC-only

   * mode and risk hardware damage if this mode is entered.

   *

   * For details, see linux-omap mailing list May 2015 thread

   *  [PATCH] ARM: dts: am335x-bone* enable pmic-shutdown-controller

   * In particular, messages:

   *  http://www.spinics.net/lists/linux-omap/msg118585.html

   *  http://www.spinics.net/lists/linux-omap/msg118615.html

   *

   * You can override this later with

   *  &tps {  /delete-property/ ti,pmic-shutdown-controller;  }

   * if you want to use RTC-only mode and made sure you are not affected

   * by the hardware problems. (Tip: double-check by performing a current

   * measurement after shutdown: it should be less than 1 mA.)
