Subject: [PATCH v4 3/7] regulator: bindings: Add properties for coupled regulators
Date: Mon, 22 Jan 2018 15:30:08 +0100	[thread overview]
Message-ID: <1516631412-17542-4-git-send-email-m.purski@samsung.com> (raw)
In-Reply-To: <1516631412-17542-1-git-send-email-m.purski-Sze3O3UU22JBDgjK7y7TUQ@public.gmane.org>

Some regulators require keeping their voltage spread below defined
max_spread.

Add properties to provide information on regulators' coupling.
