From 14e2739c3695734bb4f5a0deca6fff4e10e5ef5d Mon Sep 17 00:00:00 2001 From: Wenjing Liu Date: Thu, 20 Oct 2022 11:46:32 -0400 Subject: [PATCH] drm/amd/display: refactor enable/disable audio stream hw sequence [why] 1. As recommended by hardware team, don't enable APG when stream is not enabled. 2. Move audio stream encoder programming into link_hwss. [how] 1. Merge dp_audio_enable into enable audio stream hw sequence. 2. Move stream encoder programming into link hwss level to unify stream encoder programming interface.
