Subject: [PATCH] regulator: lochnagar: Add on_off_delay for VDDCORE
Date: Tue, 1 Oct 2019 14:20:17 +0100 [thread overview]
Message-ID: <20191001132017.1785-1-ckeepax@opensource.cirrus.com> (raw)
The VDDCORE regulator takes a good length of time to discharge down, so
add an on_off_delay to ensure DCVDD is removed before it is powered on
again.
