From 3904fb78a80da64d7fd1a4f270725a6d4272c86f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 30 Apr 2019 17:29:01 +0300 Subject: [PATCH] drm/i915: hsw+ audio regs are per-transocder MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit s/pipe/transcoder/ when dealing with hsw+ audio registers. This won't actually make any real difference since there is no audio on the EDP transcoder. But this should avoid a bit of confusion when cross checking against the spec.
