From fb00ff4c30a8cce32371e5d1abcbb33be1b6d506 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 19 Jun 2015 18:09:50 +0200 Subject: ARM: dts: imx53-qsb: select open-drain mode for i2c1 pads Both imx53-qsb and imx53-qsrb don't have external pull-up resistors on the I2C1 SCL and SDA lines populated. Select open-drain mode and enable the internal pull-up for both.
