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);
This should be replaced with u32_replace_bits(), i am sending the fix
Gah.
should have caught this :(
