From e6f607bb2ba8aac719cf6abdf1d9dd8dae0c63e5 Mon Sep 17 00:00:00 2001 From: Fabrizio Castro Date: Wed, 18 Dec 2019 01:07:53 +0200 Subject: drm/bridge: lvds-codec: Add "lvds-decoder" support Add support for transparent LVDS decoders by adding a new compatible string ("lvds-decoder") to the driver. This patch also adds member connector_type to struct lvds_codec, and that's because LVDS decoders have a different connector type from LVDS encoders. We fill this new member up with the data matching the compatible string.
