From a1c8a5512b7cddc81767172f0de37b155cea039f Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Mon, 24 Nov 2014 14:10:52 +0000 Subject: regulator: core: Add PRE_DISABLE notification Add a PRE_DISABLE notification so that consumers can use a notifier to run any steps required to prepare for the regulator being switched off. Since the regulator disable can fail an abort notification is also added.
