Subject: ALSA: hda - Add support of auto-parser to cxt5047 / CX20551 Waikiki
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fa5dadcbe00fd6c86a149df886d4ae2cc30c33ef;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Add support of auto-parser to cxt5047 / CX20551 Waikiki

Similarly like other Conexant codecs, now model=auto is supported for
cxt5047.

But the auto-parser mode isn't activated as default yet, since BIOS
pin-configs seem often broken on machines with this codec.  User need
to pass model=auto explicitly.
