[PATCH v2 0/4] Support additional regulators on BCM590xx

[PATCH v2 0/4] Support additional regulators on BCM590xx

[Matt Porter]

Changes since v1:
	- Fix a several commit log typos and capitalization
	- Drop use of addmap[0|1] in favor of i2c_[pri|sec]
	- Replace regmap[0|1] with regmap_[pri|sec]

This series enables support for 7 additional regulators on the BCM59056
PMU. These regulators are accessed via a secondary I2C slave address.
The MFD driver exposes an additional regmap descriptor for the additional
address space and the regulator implements support for GPLDO1-6 and VBUS
regulators.

Matt Porter (4):
  mfd: bcm590xx: update binding with additional BCM59056 regulators
  mfd: bcm590xx: add support for secondary I2C slave address
  regulator: bcm590xx: add support for regulators on secondary I2C slave
  ARM: dts: bcm590xx: add support for GPLDO and VBUS regulators

[PATCH v2 3/4] regulator: bcm590xx: add support for regulators on secondary I2C slave

[Matt Porter]

The bcm590xx MFD driver now exposes a secondary regmap descriptor
making the registers for regulators on the secondary I2C slave address
available.  Add support for GPLDO1-6 and VBUS regulators found within
this register range.

Nice, flows much better now.

Can I just apply the two MFD patches, or are there cross-deps?

There's cross-deps so the regulator driver will need to go with it.
Mark mentioned earlier in the thread that he wanted to merge through
the regulator tree though.

Can someone please send me whatever it is you want me to look at, the
above diffstat doesn't look relevant.  Given the frequency of respins
I'm not always paying a huge amount of attention to MFD serieses which
look like they're going to be resent.

The series has cross dependencies (shared header include) and thus needs
to have both the mfd and regulator portions merged together. You had
mentioned in the v1 version that you'd like to take it through the
regulator tree and so Lee's comments earlier were with regard to you
taking the mfd portions.

The series has cross dependencies (shared header include) and thus needs
to have both the mfd and regulator portions merged together. You had
mentioned in the v1 version that you'd like to take it through the
regulator tree and so Lee's comments earlier were with regard to you
taking the mfd portions.

Right, OK - because it depends on the earlier MFD patches (I think?) I
was expecting it to be applied in MFD and merged over to regulator.

I'm not going to apply this with the rest of the set.  It will have to
go in via your normal arch/arm route.

What do these empty nodes do in any case?

Don't you at least need a status property in there or something?

They instantiate regulators. The bcm590xx binding specifies the
allowable subnode names permitted here. This replaces the old method
of specifying an index or the deprecated regulator-compatible property.
The board-specific dts includes this dtsi and applies any board
constraints to a subset of regulators that need them. Unused regulators
are all disabled which is what we want.

Not necessary for these subnodes.
