Subject: [PATCH v7 17/23] drm: bridge: dw_hdmi: Declare bridge CEC notifier support
Date: Mon, 18 May 2026 18:01:53 +0000	[thread overview]
Message-ID: <20260518180206.2480119-18-jonas@kwiboo.se> (raw)
In-Reply-To: <20260518180206.2480119-1-jonas@kwiboo.se>

EDID and CEC phys addr is now being updated in bridge detect() func,
making it possible to have CEC notifier support using the bridge
connector.

Add the CEC notifier bridge op to instruct the bridge connector to make
use of the generic CEC notifier helpers.
