Subject: [PATCH 1/4] ARM: cfa10036: dt: Change i2c0 clock frequency
Date: Mon, 22 Apr 2013 12:02:22 +0200 [thread overview]
Message-ID: <1366624945-5708-2-git-send-email-maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <1366624945-5708-1-git-send-email-maxime.ripard@free-electrons.com>
The OLED display can work faster. Change the i2c controller clock
frequency to remove the tearing effect that can be seen on the display.
