No, the backward compatibility here is only useful for drivers which
used "ti,system-power-controller" in the past and recently switched to
the new property through the standard helper function. As most of the
dts were not updated to use the new property, previous patches broke
compatibility with "ti,system-power-controller" (this compat would be
reverted with this serie). Only one driver has this problem, it is
tps65910.

So, What you propose is that I should handle the old property directly
from tps65910, and keep the standard helper generic right ?
