Subject: [PATCH 5/7] drm/mediatek: mtk_dsi: Use simple encoder
Date:   Wed,  8 Apr 2020 23:11:18 +0200
Message-Id: <20200408211120.1407512-6-enric.balletbo@collabora.com>
In-Reply-To: <20200408211120.1407512-1-enric.balletbo@collabora.com>

Precedence: bulk

The mtk_dsi driver uses an empty implementation for its encoder. Replace
the code with the generic simple encoder.
