Subject: [PATCH v2 2/3] backlight: tdo24m: add the reset line gpio
Date: Fri, 13 Oct 2017 21:42:48 +0200	[thread overview]
Message-ID: <20171013194250.9001-2-robert.jarzmik@free.fr> (raw)
In-Reply-To: <20171013194250.9001-1-robert.jarzmik@free.fr>

The Toppoly panels have a global reset line. Add an optional gpio
control for this line, for platforms which have the ability to drive it.
