From b87a9a128bf00e496376c038f51c638b12782833 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 26 Oct 2022 20:01:38 +0300 Subject: [PATCH] drm/i915/audio: Remove CL/BLC audio stuff MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We don't use the audio code on crestline (CL) since it doesn't support native HDMI output, and SDVO has it's own way of doing audio. And Bearlake-C (BLC) doesn't even exist in the real world, so no point it trying to deal with it.
