Subject: [PATCHv2 1/3] dt-bindings: display: dw_hdmi.txt: add cec-disable property
Date: Fri, 23 Mar 2018 13:59:13 +0100 [thread overview]
Message-ID: <20180323125915.13986-2-hverkuil@xs4all.nl> (raw)
In-Reply-To: <20180323125915.13986-1-hverkuil@xs4all.nl>
From: Hans Verkuil <hans.verkuil@cisco.com>
Some boards have both a DesignWare and their own CEC controller.
The CEC pin is only hooked up to their own CEC controller and not
to the DW controller.
Add the cec-disable property to disable the DW CEC controller.
This particular situation happens on Amlogic boards that have their
own meson CEC controller.
