Subject: Regmap group read and write issue for special case of PMIC

Hi,

DA9052/53 PMIC in SPI mode does not support group read and write but in
I2C mode group read and write are supported.

This special case of DA9052/53 like PMIC needs to be handled in the
regmap. For this can we, in regmap introduce a new flag and its value
determines whether to translate internally, the regmap group read and
write call into a series of single read and write calls Or not?

Regards,
Ashish
