/* restore registers by regcache_sync */fsl_esai_register_restore(esai_priv);regmap_update_bits(esai_priv->regmap, REG_ESAI_TCR,ESAI_xCR_xPR_MASK, 0);regmap_update_bits(esai_priv->regmap, REG_ESAI_RCR,ESAI_xCR_xPR_MASK, 0);And just for curious, can (or shall) we stuff this personal reset to the reset() function? I found this one is a part of the reset routine being mentioned in the RM -- it was done after ESAI reset is done via ECR register.
There is a problem to do this, TPR/RPR need to be clear after configure the control register. (TCCR, TCR). So it seems not only one place (reset function) need to be changed.
