Hi Mark and Lars,
commit 9d863b88ec371491e926e0828dbe3d36ead0f6f9 Author: Lars-Peter Clausen lars@metafoo.de Date: Sat Aug 31 18:15:23 2013 +0200
ASoC: ssm2602: Fix cache sync The ssm2602 uses regmap for caching not soc-cache, so we need to use regcache_sync() instead of snd_soc_cache_sync().According my test, regcache_sync() can't recover register values when resume. While snd_soc_cache_sync() works fine. I used regmap_read() to read registers in regmap layer and found it's the same as suspend. But regcache_sync() didn't sync these registers correctly to hardware.
That does not make too much sense. snd_soc_cache_sync() is definitely a no-op when using regmap. Which kernel version are you on? Are there any additional changes to this driver in your tree?
