SubjectRe: [PATCH v2 1/3] soundwire: qcom: clear BIT FIELDs before value set.
From
Date

>> According to usage (bitfields.h) of REG_FIELDS,
>> Modify is:
>> reg &= ~REG_FIELD_C;
>> reg |= FIELD_PREP(REG_FIELD_C, c);


if this is indeed the case, all the code in cadence_master.c is also
broken, e.g:

dpn_config = cdns_readl(cdns, dpn_config_off);

dpn_config |= FIELD_PREP(CDNS_DPN_CONFIG_WL, (p_params->bps - 1));
dpn_config |= FIELD_PREP(CDNS_DPN_CONFIG_PORT_FLOW, p_params->flow_mode);
dpn_config |= FIELD_PREP(CDNS_DPN_CONFIG_PORT_DAT, p_params->data_mode);


Gah.
