Subject: [PATCH] regulator: lochnagar: Add additional VDDCORE range
Date: Fri, 4 Sep 2020 13:25:06 +0100 [thread overview]
Message-ID: <20200904122506.28017-1-ckeepax@opensource.cirrus.com> (raw)
In the case of an unrecognised mini-card the Lochnagar will not
initialise the VDDCORE voltage register leading to a value outside of the
current range. Add an additional range to cover these values, initially
this wasn't done since they are duplicates of the existing minimum
value.
