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!
