The split of HDMI codec driver may confuse users when migrating from
the previous kernel configs and leave some drivers disabled
unexpectedly. Although we've already set y to all HDMI codec drivers
as default, it's still safer to paper over the wrong choices.
This patch marks the prompt of each HDMI codec driver with
CONFIG_EXPERT, so that they are all enabled when the top-level
CONFIG_SND_HDA_CODEC_HDMI is set.
For users who really care about the minimalistic configuration, they
can turn each driver on/off individually after setting
CONFIG_EXPERT=y.
The patch also adds the missing help text to the top-level
CONFIG_SND_HDA_CODEC_HDMI together with the explanation of individual
choices, too.

Say Y to enable HD-Audio Keep Alive (KAE) aka Silent Stream
|
|
for HDMI on hardware that supports the feature.
|
|
|
|
When enabled, the HDMI/DisplayPort codec will continue to provide
|
|
a continuous clock and a valid but silent data stream to
|
|
any connected external receiver. This allows to avoid gaps
|
|
at start of playback. Many receivers require multiple seconds
|
|
to start playing audio after the clock has been stopped.
|
|
This feature can impact power consumption as resources
|
|
are kept reserved both at transmitter and receiver.
