Subject: [PATCH v7 2/6] regulator: bindings: Add properties for coupled regulators
Date: Mon, 23 Apr 2018 16:33:38 +0200 [thread overview]
Message-ID: <1524494022-22260-3-git-send-email-m.purski@samsung.com> (raw)
In-Reply-To: <1524494022-22260-1-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.
