Subject: [RESEND PATCH v2 3/3] ARM: dts: imx28-cfa10036: Fix the reset gpio signal polarity
Date: Thu, 27 Sep 2018 09:24:41 +0000 [thread overview]
Message-ID: <1538040281-21319-3-git-send-email-michal.vokac@ysoft.com> (raw)
In-Reply-To: <1538040281-21319-1-git-send-email-michal.vokac@ysoft.com>
The reset signal of the SSD1306 OLED display is actually active-low.
Adapt the DT to reflect the real world.
