[alsa-devel] [PATCH 1/5] ALSA: hda: add verbs for stripe control

Controllers can support multiple Serial Data Out(SDO) lines, for
extended outbound bandwidth, to pump data to all codecs on the link.
Codecs can sample data present on SDO.

Add verbs AC_VERB_GET_STRIPE_CONTROL and AC_VERB_SET_STRIPE_CONTROL
These can be used to program usage of SDO lines for codec.
