[PATCH] ARM: dts: am335x-boneblack: disable RTC-only sleep

[Matthijs van Duin]

Sorry for the late response, I only just noticed this since I wasn't CC'd.

This "fix" was not ever Reported-By or Tested-By me as it claims. It
is in fact wrong: &rtc { system-power-controller; } needs to be
present for every variety of beaglebone (more generally every design
with a TPS65217 whose PWR_EN is connected to the PMIC_POWER_EN pin of
an AM335x).

Without a system-power-controller, the kernel has no way of turning
off the system and shutdown will leave the system halted instead.

The previously posted fix, which added  &tps {
ti,pmic-shutdown-controller; }  was correct, and ensures that a
poweroff makes the pmic enter "OFF-state" rather than "SLEEP-state"
(aka RTC-only sleep).
