/*
 * Intel High Definition Audio (Controller) driver for FreeBSD. Be advised
 * that this driver still in its early stage, and possible of rewrite are
 * pretty much guaranteed. There are supposedly several distinct parent/child
 * busses to make this "perfect", but as for now and for the sake of
 * simplicity, everything is gobble up within single source.
 *
 * List of subsys:
 *     1) HDA Controller support
 *     2) HDA Codecs support, which may include
 *        - HDA
 *        - Modem
 *        - HDMI
 *     3) Widget parser - the real magic of why this driver works on so
 *        many hardwares with minimal vendor specific quirk. The original
 *        parser was written using Ruby and can be found at
 *        http://people.freebsd.org/~ariff/HDA/parser.rb . This crude
 *        ruby parser take the verbose dmesg dump as its input. Refer to
 *        http://www.microsoft.com/whdc/device/audio/default.mspx for various
 *        interesting documents, especially UAA (Universal Audio Architecture).
 *     4) Possible vendor specific support.
 *        (snd_hda_intel, snd_hda_ati, etc..)

 * Thanks to Ahmad Ubaidah Omar @ Defenxis Sdn. Bhd. for the
 * Compaq V3000 with Conexant HDA.
