[PATCH V4 1/2] mfd: Add ROHM BD9571MWV-M PMIC DT bindings

[Marek Vasut]

Add DT bindings for the ROHM BD9571MWV-M PMIC. This PMIC has
the following features:
- multiple voltage monitors for 1V8, 2V5, 3V3 voltage rail
- one voltage regulator for DVFS
- two GPIOs

V2: - Drop the compatible = "regulator-fixed" from the binding example,
      it should not be there.
    - List the VD09 regulator
V3: Replace bd9571@30 with pmic@30
V4: No changes

[PATCH V4 2/2] mfd: Add ROHM BD9571MWV-M MFD PMIC driver

[Marek Vasut]

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.

V2: - Change BD9571MWV_AVS_VD09_VID0,1,2,3 to BD9571MWV_AVS_VD09_VID(n)
    - Change BD9571MWV_AVS_DVFS_VID0,1,2,3 to BD9571MWV_AVS_DVFS_VID(n)
    - Make the AVS_VD09 range RW, so it can be used by the regulator
      driver for the VD09 regulator
    - Report the regmap read return values when attempting to read ID
      registers fails
V3: No change
V4: select REGMAP_IRQ
