From 3a8ed20db88923988640d64ff47da2a07c5c1063 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 27 Jun 2017 01:58:32 -0700 Subject: [PATCH] ARM: dts: Disable HDMI CEC internal pull-ups Devices using an external encoder, ESD protection and level shifter such as tpd12s015 or ip4791cz12 have the CEC pull in the encoder chip. And on var-som-om44, there is external pull up resistor R30. So the internal CEC pull-up resistor needs to be disabled as otherwise the external and internal pull are parallel making the pull value much smaller than intended. This leads into the CEC not working as reported by Hans Verkuil .
