Subject: [PATCH v4 2/4] drm/msm/dp: initialize audio_comp when audio starts
Date: Wed, 21 Apr 2021 16:37:36 -0700 [thread overview]
Message-ID: <1619048258-8717-3-git-send-email-khsieh@codeaurora.org> (raw)
In-Reply-To: <1619048258-8717-1-git-send-email-khsieh@codeaurora.org>
Initialize audio_comp when audio starts and wait for audio_comp at
dp_display_disable(). This will take care of both dongle unplugged
and display off (suspend) cases.
Changes in v2:
-- add dp_display_signal_audio_start()
Changes in v3:
-- restore dp_display_handle_plugged_change() at dp_hpd_unplug_handle().
Changes in v4:
-- none
