Subject: [PATCH] drm/mediatek: mtk_dpi: Create connector for bridges
Date: Thu,  3 Dec 2020 16:24:45 +0800	[thread overview]
Message-ID: <20201203082445.1342763-1-hsinyi@chromium.org> (raw)

Similar to a9d9fea74be2 ("drm/mediatek: mtk_dsi: Create connector for bridges"):

Use the drm_bridge_connector helper to create a connector for pipelines
that use drm_bridge. This allows splitting connector operations across
multiple bridges when necessary, instead of having the last bridge in
the chain creating the connector and handling all connector operations
internally.
