From 3d0e10f2300812766e0efee283b2a0825c4b7b8c Mon Sep 17 00:00:00 2001 From: Werner Zeh Date: Wed, 21 Jul 2021 10:34:17 +0200 Subject: [PATCH] mb/siemens/mc_ehl1: Adjust I2C bus enablement in devicetree This mainboard uses I2C1 and I2C4 buses only. Disable all the others as they are not connected at all.
