From baf61639b808307bd6e5be27e5cbef9cc3acd80e Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Fri, 22 Dec 2017 18:28:59 +0800 Subject: [PATCH] power: reset: remove unused imx-snvs-poweroff driver There's no user of it in kernel now and it basically functions the same as the generic syscon-poweroff.c to which we have already switched. So let's remove it.
