In the patch series "[PATCH v4 0/3] add power off driver for i.mx6" from
Sep 26 (what I have tested) snvs_poweroff was used. This worked as expected.
So this series "[PATCH v4 0/3] add power off driver for i.mx6" (sent on
Nov 12) apparently contains old patches and is not simply resent as
stated in the cover letter.
