* mfd: bd9571mwv: Add volatile register to make DVFS workDien Pham2019-01-031-0/+1
| | | | | | | | | | | | | Because BD9571MWV_DVFS_MONIVDAC is not defined in the volatile table, the physical register value is not updated by regmap and DVFS doesn't work as expected. Fix it!

Add the MFD part of the ROHM BD9571MWV-M PMIC driver and MAINTAINERS entry. The MFD part only specifies the regmap bits for the PMIC and binds the subdevs together. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
