From 93a4c8355e0e448d83f31801b4c72f66e4360975 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 23 Aug 2017 18:24:50 +0200 Subject: ARM: dts: exynos: add needs-hpd for Odroid-XU3/4 CEC support was added for Exynos5 in 4.13, but for the Odroids we need to set 'needs-hpd' as well since CEC is disabled when there is no HDMI hotplug signal, just as for the exynos4 Odroid-U3. This is due to the level-shifter that is disabled when there is no HPD, thus blocking the CEC signal as well. Same close-but-no-cigar board design as the Odroid-U3. Tested with my Odroid XU4.
