[PATCH v3 0/5] BCM59056 PMU regulator support

[PATCH v3 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 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()

[PATCH v3 1/5] mfd: add bcm590xx pmu DT binding

[Matt Porter]

Add a DT binding for the BCM590xx PMUs. The binding inherits from
the generic regulator bindings.

[PATCH v3 2/5] mfd: add bcm590xx pmu driver

[Matt Porter]

Add a driver for the BCM590xx PMU multi-function devices. The driver
initially supports regmap initialization and instantiation of the
voltage regulator device function of the PMU.

I have a tiny nit that 'ret' doesn't need to be initialised before
use in probe(), but apart from that...

Looks pretty sensible:

Ok, thanks. When I get back in front of my desktop I'll send a v4 of
just this patch to address that nit. Mark already applied the regulator
driver from this series, will you be taking this through your tree? For
that matter, I wonder if the binding would also go through your tree
with this driver.

At least the MFD portion and the DT binding doc will go through the
MFD tree.

Are there any inter-patch dependencies in the set? If so, we should
know about them so we can coordinate a sensible solution.

Yes, the regulator driver (3/5) that Mark applied is dependent on this
patch...the regulator driver includes include/linux/mfd/bcm590xx.h.

There's no actual dependency though - the regulator driver can only be
built if the MFD is enabled in Kconfig since it depends on it so until
the MFD is present in the tree it won't get built.

Oh, right. Lee, no dependencies then.

Perfect, I'll just apply the MFD patch.

We still need the DT guys to look over your document, so nothing will
be certain until a) we receive their Ack or b) enough time passes, so
we will review it between ourselves.

[PATCH v3 3/5] regulator: add bcm590xx regulator driver

[Matt Porter]

Add a regulator driver for the BCM590xx PMU voltage regulators.
The driver supports LDOs and DCDCs in normal mode only. There is
no support for low-power mode or power sequencing.
