Hi, This patch series aims to use drm_bridge_connector in the i.MX8MP LCDIF driver so that bridge drivers don't need to initialize DRM connectors. Patch 1-3 add HDMI connectors to some i.MX8MP platforms's DT as preparation work. The Synopsys DW HDMI bridge core driver would try to find the bridge of the HDMI connector after the LCDIF driver starts to use drm_bridge_connector. Patch 4 sets output_port to 1 in i.MX8MP HDMI TX driver, as a preparation work too. The Synopsys DW HDMI bridge core driver needs to know the output port index so that the driver can use the port index to find and attach the next bridge. The next bridge attachment is needed after the LCDIF driver starts to use drm_bridge_connector. Patch 5 makes the LCDIF driver use drm_bridge_connector. With this patch set, an in-flight ITE IT6263 bridge driver[1] doesn't need to initialize a DRM connector.
