From 75034eb5e4c267d4ab93085b5d6fa3dab2535b34 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 10 Mar 2023 15:34:54 +0200 Subject: ASoC: SOF: Intel: MTL: Don't access EM2 This reverts commit 2b5a30cafb2ef ("ASoC: SOF: Intel: MTL: Enable DMI L1"). It came to our attention that the access to the EM2 register is restricted to the DSP side on MTL compared to prior platforms. Writing to it from the host side has no effect (negative or positive), it is better to remove the code to not cause confusion and wrong impression.
