From e89355ed8ddefc68e33a754fe8be067cee54ce62 Mon Sep 17 00:00:00 2001 From: Daniel Baluta Date: Wed, 19 Jun 2019 19:50:31 +0300 Subject: [PATCH] ASoC: fsl_sai: Mark cache dirty at resume This is needed so that at resume will restore the correct SAI registers. Looks like the call to regcache_mark_dirty was missed when porting commit 760bd6187413e37c8 ("MLK-15960-2: ASoC: fsl_sai: refine the pm runtime function") Signed-off-by: Daniel Baluta --- sound/soc/fsl/fsl_sai.c | 2 ++ 1 file changed, 2 insertions(+) --- a/sound/soc/fsl/fsl_sai.c +++ b/sound/soc/fsl/fsl_sai.c @@ -1617,6 +1617,8 @@ static int fsl_sai_runtime_resume(struct PM_QOS_CPU_DMA_LATENCY, 0); regcache_cache_only(sai->regmap, false); + regcache_mark_dirty(sai->regmap); + regmap_write(sai->regmap, FSL_SAI_TCSR(offset), FSL_SAI_CSR_SR); regmap_write(sai->regmap, FSL_SAI_RCSR(offset), FSL_SAI_CSR_SR); usleep_range(1000, 2000);
