Subject: [PATCH 1/4] drm/i915: Add audio set_ncts callback
Date: Thu,  6 Aug 2015 14:52:54 +0800	[thread overview]
Message-ID: <1438843977-4269-1-git-send-email-libin.yang@intel.com> (raw)

From: Libin Yang <libin.yang@intel.com>

Add the set_ncts callback.

With the callback, audio driver can trigger
i915 driver to set the proper N/CTS
based on different sample rates.
