Subject: [PATCHv2 2/3] drm: bridge: dw-hdmi: check the cec-disable property
Date: Fri, 23 Mar 2018 13:59:14 +0100	[thread overview]
Message-ID: <20180323125915.13986-3-hverkuil@xs4all.nl> (raw)
In-Reply-To: <20180323125915.13986-1-hverkuil@xs4all.nl>

From: Hans Verkuil <hans.verkuil@cisco.com>

If the cec-disable property was set, then disable the DW CEC
controller. This is needed for boards that have their own
CEC controller.
