H A D | Kconfig | 742db30c Mon Jan 13 08:17:21 CST 2020 Takashi Iwai <tiwai@suse.de> drm/nouveau: Add HD-audio component notifier support
This patch adds the support for the notification of HD-audio hotplug via the already existing drm_audio_component framework. This allows us more reliable hotplug notification and ELD transfer without accessing HD-audio bus; it's more efficient, and more importantly, it works without waking up the runtime PM.
The implementation is rather simplistic: nouveau driver provides the get_eld ops for HD-audio, and it notifies the audio hotplug via pin_eld_notify callback upon each nv50_audio_enable() and _disable() call. As the HD-audio pin assignment seems corresponding to the CRTC, the crtc->index number is passed directly as the zero-based port number.
The bind and unbind callbacks handle the device-link so that it assures the PM call order.
