Thanks. I don't receive this message before in eamil. Current regmap only support register access using several bus: i2c, spi, ac97 ... But register access for intel pmic are done by hardware ipc, so we add such support in regmap core, To make pmic subdevice drivers can use generic regmap r/w API to access registers.
