Hi,=0D

hdmi-codec allows to have a lot of HDMI-audio related infrastructure in pla=
ce,=0D
it's missing a few controls to be able to provide HBR passthrough. This ser=

default control should be a PCM one, it feels a bit weird to have two diffe=

control type for two controls so similar, and other drivers are pretty=0D
inconsistent with this. Should we update the documentation?=0D
