Subject: [PATCH 00/11] drm/vc4: hdmi: Enable Channel Mapping, IEC958, HBR Passthrough using hdmi-codec
Date: Fri, 7 May 2021 16:03:23 +0200 [thread overview]
Message-ID: <20210507140334.204865-1-maxime@cerno.tech> (raw)
Hi,
hdmi-codec allows to have a lot of HDMI-audio related infrastructure in place,
it's missing a few controls to be able to provide HBR passthrough. This series
adds more infrastructure for the drivers, and leverages it in the vc4 HDMI
controller driver.
One thing that felt a bit weird is that even though
https://www.kernel.org/doc/html/latest/sound/kernel-api/writing-an-alsa-driver.html#iec958-s-pdif
mentions that the iec958 mask control should be a mixer control and the
default control should be a PCM one, it feels a bit weird to have two different
control type for two controls so similar, and other drivers are pretty
inconsistent with this. Should we update the documentation?
Thanks!
Maxime
