Subject: [PATCH v3 3/5] drm/panel: st7703: Add media bus format
Date:   Mon, 11 Oct 2021 15:41:25 +0200
Message-Id: <d7ebeec861f4518c8497a5e07d09d5a9fd123d3d.1633959458.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.
