From 30b71761957c541cd9dfd6cd10e3feb21a8ddca1 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 7 Dec 2018 23:08:35 +0200 Subject: drm/omap: Add support for drm_panel Hook up drm_panel support in the omapdrm driver. The change is relatively simply as the way has been paved by drm_bridge support already. In addition to looking up, attaching to and detaching from the panel, we only need to add panel support in the connector .get_modes() handler, take connector bus flags (set by the panel) into account, and enable/disable the panel in the encoder enable/disable operations handlers.
