From 36478a74c7ddaf58d80da5cef9c5ddb5beed5a2e Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Tue, 20 Feb 2024 12:50:34 +0100 Subject: ASoC: Intel: avs: ICCMAX recommendations for ICL+ platforms MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For ICL+ platforms to avoid DMI/OPIO L1 entry during the base firmware load procedure, HW recommends to set LTRP_GB to 95us and start an additional CAPTURE stream in the background. Once the load completes, original LTRP_GB value is restored and the additional stream is released.
