From 05b1342f5014b7c100834ae179dd90d1a1da7366 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 21 Jul 2015 15:35:52 +0100 Subject: [PATCH] drm: bridge/dw_hdmi: clean up HDMI vs DVI mode handling The FSL kernel detects the HDMI vendor id, and uses this to set hdmi->edid_cfg.hdmi_cap, which is then used to set mdvi appropriately, rather than detecting whether we are outputting a CEA mode. Update the dw_hdmi code to use this logic, but lets eliminate the mdvi variable, prefering the more verbose "hdmi->sink_is_hdmi" instead. Use the generic drm_detect_hdmi_monitor() to detect a HDMI sink.
