Comparing with the implementation of MT6323, the following registers 
seem MT6397 only:
PWRAP_DEW_EVENT_OUT_EN
PWRAP_DEW_EVENT_SRC_EN,
PWRAP_DEW_EVENT_SRC
PWRAP_DEW_EVENT_FLAG
PWRAP_DEW_MON_FLAG_SEL
PWRAP_DEW_EVENT_TEST
PWRAP_DEW_CIPHER_LOAD
PWRAP_DEW_CIPHER_START

Can you please check that and put the ones which are really MT6397 only 
in a separate paragraph?

Thanks,
Matthias
