Subject: [PATCH v1 4/5] drm/panel: mantix: Add media bus format
Date:   Tue, 28 Sep 2021 14:16:11 +0200
Message-Id: <91f413a0fa8d0a3b1805cc1fa27b46ede49545d7.1632828477.git.agx@sigxcpu.org>

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

This allows the DSI bridge to detect the correct bus format.
We currently only support MEDIA_BUS_FMT_RGB888_1X24.
