[alsa-devel] [PATCH 1/2] ALSA: hda/hdmi - set depop_delay for haswell plus
From: Libin Yang libin.yang@intel.com
Both Haswell and Broadwell need set depop_delay to 0. So apply this setting to haswell plus.

From: Libin Yang libin.yang@intel.com
Valleyview and Cherryview have the same behavior on display audio. So this patch defines is_valleyview_plus() to include codecs for both Valleyview and its successor Cherryview, and apply Valleyview fix-ups to Cherryview.
