Subject: [PATCH v6 2/6] regulator: bindings: Add properties for coupled regulators
Date: Fri, 09 Mar 2018 13:22:04 +0100 [thread overview]
Message-ID: <1520598128-11768-3-git-send-email-m.purski@samsung.com> (raw)
In-Reply-To: <1520598128-11768-1-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.
