Subject: [PATCH 1/2] dt-bindings: display: faraday,tve200: Use a level-high interrupt
Date: Mon, 21 Sep 2026 11:15:54 +0200 [thread overview]
Message-ID: <20260921-gemini-tve200-fix-v1-1-8be03ac2a8f7@kernel.org> (raw)
In-Reply-To: <20260921-gemini-tve200-fix-v1-0-8be03ac2a8f7@kernel.org>
The TVE200 vertical interrupt can remain pending after acknowledgment.
Using rising-edge triggering can leave it unserviced when no new edge
is generated, causing vblank and page-flip timeouts on the D-Link DIR-685.
Use level-high triggering in the binding example so a pending interrupt
is delivered again without requiring a new edge.
Fixes: 8b17e80d9e46 ("drm/tve200: Add DT bindings")
