[Intel-gfx] [PATCH v4 3/3] drm/i915: Haswell HDMI audio enable
Wang Xingchao

Mon Aug 6 12:44:00 CEST 2012
Configure the related HDMI audio register to generate an unsolicited
response to the audio controller driver to indicate that the controller
sequence should start.
Use "pipe" way to get correct register definitions for IBX/CPT/HSW.
