From 4520aa2891263736791861c1fa12dd8f0c34a19e Mon Sep 17 00:00:00 2001 From: Karthikeyan Ramasubramanian Date: Fri, 23 Apr 2021 11:42:19 -0600 Subject: soc/amd/common/acp: Move Audio Co-processor driver to common Audio Co-processor driver is similar for both Picasso and Cezanne SoCs. Hence move it to the common location. BUG=None. TEST=Builds Dalboz, Trembyle, Vilboz, Mandolin and Bilby mainboards.
