Subject: [PATCH] Enumerate only the available timings
Date: Fri, 30 May 2025 12:17:20 +0200 [thread overview]
Message-ID: <20250530101720.1663-1-tumic@gpxsee.org> (raw)
From: Martin Tůma <martin.tuma@digiteqautomotive.com>
Enumerate only the available (as given by the sysfs setup - our "EDID
replacement") timings, not all theoretically possible. This is the video
outputs part of the previous inputs patch that somehow got "lost in
translation".
