From e4a3b8cf40713d6511391de3286ccba38998756b Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Wed, 2 Aug 2023 10:36:23 -0500 Subject: ASoC: rt715-sdca: enable pm_runtime in probe, keep status as 'suspended' This patch suggests enabling pm_runtime during the probe, but marking the device as 'active' only after it is enumerated. That will force a dependency between the card and the codec, pm_runtime_get_sync() will have to wait for the codec device to resume and hence implicitly wait for the enumeration/initialization to be completed. In the nominal case where the codec device is already active the get_sync() would only perform a ref-count increase. The changes are directly inspired by RT711 and RT711-sdca changes.
