Subject: [PATCH 0/2] drm/meson: fix hdmi auxiliary system operation without display
Date: Fri, 26 Apr 2024 18:02:52 +0200 [thread overview]
Message-ID: <20240426160256.3089978-1-jbrunet@baylibre.com> (raw)
CEC and ARC should work even when HDMI is not actively used for the
display but it is not the case with Amlogic HDMI.
This is important for devices such as sound bars which may use DSI
to display a UI and HDMI for CEC/ARC. A display is not required for these
functions
This patchset fixes the problem.
