From: Lucas Tanure <tanureal@opensource.cirrus.com>

Dolphin devices have CS8409 HDA Bridge connected to two CS42L42 codecs.
Codec 1 supports Headphone and Headset Mic.
Codec 2 supports Line Out.

Features:
 - Front and Read Jacks appear as separate jacks; Removal or connection
   of on jack should not affect the connection of the other.
 - Front Jack only shows up on jack detection.
 - Rear Jack is Phantom Jack.
 - Separate Volume Controls for each Jack
