If anyone has any objections, please let me know. ------------------ From: Shengjiu Wang [ Upstream commit 0e270f32975fd21874185ba53653630dd40bf560 ] Use the regmap_write() for software reset in fsl_sai_config_disable would cause the FSL_SAI_CSR_BCE bit to be cleared. Refer to commit 197c53c8ecb34 ("ASoC: fsl_sai: Don't disable bitclock for i.MX8MP") FSL_SAI_CSR_BCE should not be cleared. So need to use regmap_update_bits() instead of regmap_write() for these bit operations.
