Subject: [RFC PATCH v2 1/3] regulator: bindings: Add properties for coupled regulators
Date: Wed, 18 Oct 2017 14:47:00 +0200 [thread overview]
Message-ID: <1508330822-8039-2-git-send-email-m.purski@samsung.com> (raw)
In-Reply-To: <1508330822-8039-1-git-send-email-m.purski@samsung.com>
Some regulators require keeping their voltage spread below defined
max_spread.
Add properties to provide information on regulators' coupling.
