Subject: [PATCH] ARM: dt: tegra: paz00: configure power off
Date: Sat, 12 Mar 2016 00:00:00 +0300 [thread overview]

Add DT property to tell the regulator that it should provide
the pm_power_off() implementation. This fix "shutdown" issue
on this device.

Tested on current mainline version, ac100 models 116 and 117,
successful rate of "shutdown" increased from 10% to 90%.
