The patch below does not apply to the 5.18-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.

Indeed, there's a dependency on

2a68ff846164 ("ASoC: SOF: Intel: hda: Revisit IMR boot sequence")

as well as the definitions added in the same patchset.

7a5974e035a6 ("ASoC: SOF: pm: add definitions for S4 and S5 states ") 6639990dbb25 ("ASoC: SOF: pm: add explicit behavior for ACPI S1 and S2 ")

will send the backport shortly.

thanks,

From 391153522d186f19a008d824bb3a05950351ce6c Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com Date: Thu, 16 Jun 2022 15:18:18 -0500 Subject: [PATCH] ASoC: SOF: Intel: disable IMR boot when resuming from ACPI S4 and S5 states MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit

The IMR was assumed to be preserved when suspending to S4 and S5 states, but community reports invalidate that assumption, the hardware seems to be powered off and the IMR memory content cleared.

Make sure regular boot with firmware download is used for S4 and S5.
