From 1a4e73915a7553d7ffb4f365b8a671bb2fa1f7ef Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 6 Sep 2022 18:01:02 +0100 Subject: ASoC: codecs: rx-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. Along with this remove a swr_reset redundant flag.
