From afd8f77957e3e83adf21d9229c61ff37f44a177a Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Tue, 26 Jul 2022 15:05:23 +0200 Subject: [PATCH] ARM: dts: imx6qdl-kontron-samx6i: hook up DDC i2c bus i2c2 is routed to the pins dedicated as DDC in the module standard. Reduce clock rate to 100kHz to be in line with VESA standard and hook this bus up to the HDMI node.
