[alsa-devel] [PATCH v2 00/12] ASoC: intel: add device_link to HDMI audio
From: Libin Yang libin.yang@intel.com
This patchset add the device_link between the machine devices of intel boards and HDMI audio codec. This can make sure that display audio power domain is always turned on before operating on the HDMI audio codecs.

From: Libin Yang libin.yang@intel.com
In resume from S3, HDAC HDMI codec driver dapm event callback may be operated before HDMI codec driver turns on the display audio power domain because of the contest between display driver and hdmi codec driver.
This patch adds the device_link between skl_nau88l25_ssm4567 machine device(consumer) and hdmi codec device (supplier) to make sure the sequence is always correct.
