Subject: [PATCH v4 5/6] dt: bindings: lm3692x: Add ti,brightness-mapping-exponential property
Date: Mon, 6 Jan 2020 16:48:54 +0100 [thread overview]
Message-ID: <3da232fdab3112a54d63bd42d5100c921d5b8b20.1578324703.git.agx@sigxcpu.org> (raw)
In-Reply-To: <cover.1578324703.git.agx@sigxcpu.org>
This allows to select exponential brightness mode instead of the default
linear mode.
