From e00a5caafac0276ea5f6ab3999087e9d3fe6ee7e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 26 Feb 2020 13:24:39 +0200 Subject: [PATCH] drm/bridge: tfp410: Allow operation without drm_connector The tfp410 driver can operate as part of a pipeline where the drm_connector is created by the display controller. Enable this mode of operation by skipping creation of a drm_connector internally.
