280 * Configure pmic to enter OFF-state instead of SLEEP-state ("RTC-only
281 * mode") at poweroff. Most BeagleBone versions do not support RTC-only
282 * mode and risk hardware damage if this mode is entered.
284 * For details, see linux-omap mailing list May 2015 thread
285 * [PATCH] ARM: dts: am335x-bone* enable pmic-shutdown-controller
286 * In particular, messages:
287 * http://www.spinics.net/lists/linux-omap/msg118585.html
288 * http://www.spinics.net/lists/linux-omap/msg118615.html
290 * You can override this later with
291 * &tps { /delete-property/ ti,pmic-shutdown-controller; }
292 * if you want to use RTC-only mode and made sure you are not affected
293 * by the hardware problems. (Tip: double-check by performing a current
294 * measurement after shutdown: it should be less than 1 mA.)
