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.
Thanks! Maxime
Changes from v1: - Added an extra patch to clarify the iec958 controls iface policy - Added kerneldoc for the new iec958 PCM functions - s/EXPORT_SYMBOL/EXPORT_SYMBOL_GPL - Used the ALSA prefix where relevant - Rebased on drm-misc-next-2021-05-17
