Subject: [PATCH v3 12/15] ASoC: hdac_hdmi: Add codec suspend/resume handler
Date: Tue, 8 Dec 2015 02:54:26 +0530 [thread overview]
Message-ID: <1449523469-4395-12-git-send-email-subhransu.s.prusty@intel.com> (raw)
In-Reply-To: <1449523469-4395-1-git-send-email-subhransu.s.prusty@intel.com>
From: Jeeja KP <jeeja.kp@intel.com>
Need to add enabling of all pins and DP1.2 feature again after
resume. Also during the device in suspended state ELD notify
callback is not processed. So add ELD check for all pins here.
