Subject: [PATCH 2/5] drm/omap: hdmi4: switch to the cec bridge ops
Date: Thu, 11 Feb 2021 11:37:00 +0100	[thread overview]
Message-ID: <20210211103703.444625-3-hverkuil-cisco@xs4all.nl> (raw)
In-Reply-To: <20210211103703.444625-1-hverkuil-cisco@xs4all.nl>

Implement the new CEC bridge ops. This makes it possible to associate
a CEC adapter with a drm connector, which helps userspace determine
with cec device node belongs to which drm connector.
