Subject: [PATCH v3 3/9] dt: bindings: lm3692x: Add ti,brightness-mapping-exponential property
Date: Sat, 4 Jan 2020 11:54:19 +0100 [thread overview]
Message-ID: <7df957d4f7902a5d2a30695ab2a5de19eb7772d3.1578134779.git.agx@sigxcpu.org> (raw)
In-Reply-To: <cover.1578134779.git.agx@sigxcpu.org>
This allows to select exponential brightness mode instead of the default
linear mode.
