[PATCH v4 0/5] BCM59056 PMU regulator support

[Matt Porter]

The BCM59056 is a multi-function power management unit used with the
BCM281xx family of SoCs. This series adds an MFD and voltage regulator
driver to support the BCM59056. The bcm28155-ap DT support is updated
to enable use of regulators on the otg and sdhci peripherals.

Changes since v3:
	- remove needless init of local ret variable in mfd driver probe

Changes since v2:
	- Move to mfd_add_devices() approach, eliminating representation
	  of the regulator block as a hardware subdevice. Regulators are
	  listed in the PMU binding and referenced via the parent device
	  of_node by the regulator driver.
	- Allow mfd driver to build as module
	- Remove regulator constraints from the .dtsi include only the
	  board-specific constraints in the board .dts.

Changes since v1:
        - renamed to bcm590xx to accomodate future family parts
        - remove use of subsys_initcall
        - fix BCM590XX_MAX_REGISTER value
        - remove unused chip id in mfd of/i2c matching
        - switch to of_platform_populate() in mfd
        - update binding to single document with regulators as optional
          properties in the regulator subdevice IP description
        - remove unused regulator get/set mode ops
        - remove unneeded regulator NULL constraint check
        - regulators property is optional, allow the driver to probe
          when it is missing
        - move of_node presence check into bcm590xx_parse_dt_reg_data()
