From fdc972d4a754b32cdf05294669ae0d6036242826 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 6 Sep 2022 18:01:01 +0100 Subject: [PATCH] ASoC: codecs: wsa-macro: handle swr_reset correctly Reset soundwire block on frame sync generation clock reset. Without this we are hitting read/write timeouts randomly during runtime pm.
