Subject: [PATCH 0/9] ASoC: mediatek: mt2701: HDMI audio support
Date: Wed, 15 Apr 2026 16:23:17 +0100 [thread overview]
Message-ID: <cover.1776265610.git.daniel@makrotopia.org> (raw)
This series wires up on-chip HDMI audio on MT2701 and MT7623, from the
DRM bridge down through the AFE into a small machine driver that binds
the AFE HDMI BE to the HDMI TX codec already exposed by the
mediatek-drm-hdmi driver. Bindings, DT and a BananaPi R2 board node
are included.
In order to survive vblank or late hotplug of the monitor, the fix
submitted separately [1] is required as well.
Everything here was developed for and tested on a BananaPi R2
(MT7623N), which turns ten years old this year -- a nice occasion to
finally land native HDMI audio for a SoC which was truly ahead of its
time.
