Now this is a bit of a mess.
There's a commit in the mfd tree, 25f833c1171d ("mfd: tps65910: Convert
ti,system-power-controller DT property to poweroff-source"), which
breaks all dts using tps65910 since these are never updated to the now
retracted property name ("poweroff-source").
This one should simply be reverted ASAP.

Romain, what tree is this patch against? The changes to the tps65910
driver appears not to even be in the regulator tree, yet you asked Mark
to merge this. And the MFD maintainer is not even on CC.
Let's fix the breakage by reverting the offending commit in mfd. Then the
new standard name can be introduced in regulator alone (e.g. this patch
without the tps65910 bits) as nothing outside of regulator should be
using the new power-off feature (or binding) for act8865. Then other
drivers and dts can be converted to use the new property name (while
retaining backwards compatibility) for 3.20.
[ We should probably also consider adding an "of_device_is_" prefix to
the helper name for consistency. ]
