From d9252772cdc811beedabbcf21ef856d09b87d1dd Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Mon, 19 Sep 2022 13:53:50 +0200 Subject: [PATCH] ASoC: SOF: Intel: hda: override mclk_id after parsing NHLT SSP blob The NHLT is already used to determine which SSP is connected to an audio codec, we can parse the SSP blob to get the mclk_id from NHLT.
