Subject: [PATCH] ARM: dts: imx6qdl-wandboard-revd1: Make EDID functional
Date: Tue, 7 Nov 2017 12:29:31 -0200	[thread overview]
Message-ID: <1510064971-18755-1-git-send-email-fabio.estevam@nxp.com> (raw)

There are 0 ohm resistors that allow selecting the EDID I2C port to
be I2C1 or I2C2.

On revd1 the 0 ohm resistors are populated in such a way that the I2C2
is used as DDC I2C bus, so fix it accordingly.
