Subject: [PATCH 0/2] Fix Gemini TVE200 interrupt triggering
Date: Mon, 21 Sep 2026 11:15:53 +0200 [thread overview]
Message-ID: <20260921-gemini-tve200-fix-v1-0-8be03ac2a8f7@kernel.org> (raw)
Rising-edge IRQ triggering can stall TVE200 interrupt delivery on the
D-Link DIR-685, causing vblank and page-flip timeouts and delayed fbcon
startup.
Set the interrupt to level-high in gemini.dtsi and correct the binding
example. The updated attached device tree supplies the correct trigger
type, leaving the DRM driver unchanged.
Level-high operation was verified on the DIR-685 with cold and warm boots.
