Subject: [PATCH 0/4] drm_audio_component support for AMD/ATI HDMI codecs
Date: Mon, 23 Jul 2018 16:50:26 +0200 [thread overview]
Message-ID: <20180723145030.25133-1-tiwai@suse.de> (raw)
Hi,
this is a patch set to add the support of drm_audio_component for
AMD/ATI HDMI codecs. With the drm_audio_component, the HDMI/DP audio
hotplug and ELD read-out can be achieved directly without the hardware
access. The best point by that is that it makes the hotplug
notification working even during runtime suspend.
The support is totally optional and dynamic, hence it still works even
if either HD-audio or DRM side isn't patched, and it'll fall back to
the existing method.
The current patch supports only radeon and a part of amdgpu; the DC
support isn't included yet.
Takashi
