From 5fdb7c4c7f2691efd760b0b0dc00da4a3699f1a6 Mon Sep 17 00:00:00 2001 From: Nicholas Kazlauskas Date: Fri, 28 Jun 2019 13:39:41 -0400 Subject: [PATCH] drm/amd/display: Expose audio inst from DC to DM [Why] In order to give pin notifications to the sound driver from DM we need to know whether audio is enabled on a stream and what pin it's using from DC. [How] Expose the instance via stream status if it's a mapped resource for the stream. It will be -1 if there's no audio mapped.
