Subject: [PATCH 1/2] ARM: dts: imx51-babbage: Fix the DVI output description
Date: Thu, 12 Dec 2019 14:17:03 -0300	[thread overview]
Message-ID: <20191212171704.23604-1-festevam@gmail.com> (raw)

imx51-babbage has a TFP410 chip that receives 24-bit RGB parallel
input and convert it to DVI.

Fix the device tree description to reflect the real hardware.
