[PATCH RESEND v6 0/6] mfd: axp20x: add AXP221 PMIC support

[Chen-Yu Tsai]

Hi Lee,

This is a resend of the AXP221 PMIC series, rebased onto the latest
for-mfd-next.

Original changelog

Changes since v5:

    - Rebased onto mfd-for-next (ba867bc60a44)

    - Dropped dts patches

    - Removed double line spacing

Changes since v4:

  - Rebased onto v4.0-rc1 and axp20x bindings v10

  - Dropped regulator set registration patches

  - Group regmap ranges/tables by AXP variant

  - Fix AXP221 interrupt numbers to match datasheet

  - Handle AXP variants when setting DC-DC regulator work mode

  - Add "switch" type regulator DC1SW, which is a secondary output
    of DCDC1 with a separate on/off switch.

  - Add AXP221 to DT bindings


Regards
ChenYu

[PATCH RESEND v6 1/6] mfd: axp20x: add AXP22x PMIC support

[Chen-Yu Tsai]

From: Boris BREZILLON <boris.brezillon-wi1+55ScJUtKEb57/3fJTNBPR1lH4CV8@public.gmane.org>

Add support for the AXP22x PMIC devices to the existing AXP20x driver.
This includes the AXP221 and AXP223, which are identical except for
the external data bus. Only AXP221 is added for now. AXP223 will be
added after it's Reduced Serial Bus (RSB) interface is supported.

AXP22x defines a new set of registers, power supplies and regulators,
but most of the API is similar to the AXP20x ones.

A new irq chip definition is used, even though the available interrupts
on AXP22x is a subset of those on AXP20x. This is done so the interrupt
numbers match those on the datasheet.

This patch only enables the interrupts, system power-off function, and PEK
sub-device. The regulator driver must first support different variants
before we enable it from the mfd driver.

Hi Lee,

I've asked Mark about merging the regulator patches through the mfd tree
(in the 4th patch). If he agrees, could you take the whole series?

Thanks.

ChenYu

These sorts of messages are best left in PATCH 0/X rather than hidden
in a random patch.  But yes, I'll take these patches though the MFD
tree.  It's too late to take, test and send out pull-requests for v4.1
now, but I will take them in once the merge-window closes.

[PATCH RESEND v6 2/6] mfd: axp20x: update DT bindings with AXP22x compatibles

[Chen-Yu Tsai]

Add AXP221 to the list of supported devices.

Also replace any mention of AXP20x in the document with a
generic "PMIC".

[PATCH RESEND v6 3/6] regulator: axp20x: prepare support for multiple AXP chip families

[Chen-Yu Tsai]

From: Boris BREZILLON <boris.brezillon-wi1+55ScJUtKEb57/3fJTNBPR1lH4CV8@public.gmane.org>

Rework the AXP20X_ macros and probe function to support the several chip
families, so that each family can define it's own set of regulators.

[PATCH RESEND v6 4/6] regulator: axp20x: add support for AXP22X regulators

[Chen-Yu Tsai]

From: Boris BREZILLON <boris.brezillon-wi1+55ScJUtKEb57/3fJTNBPR1lH4CV8@public.gmane.org>

Add AXP22X regulator definitions and variant id associations.
This introduces a new "switch" type output for one of the regulators.
It is a switchable secondary output of one regulator, with the same
voltage level as the primary output.

Hi Mark,
    
This patch depends on the previous patch "regulator: axp20x: prepare
support for multiple AXP chip families" and the mfd header from the
first patch "mfd: axp20x: add AXP22x PMIC support".

Could we merge both regulator patches through the mfd tree, with the
other patches in the series? There are no other external dependencies.

ChenYu

Yes, of course we can - that's the whole point of me sending a

the number of reposts of MFD series I get sent :(

Okay, I'm ready to take this now.

Mark,

  Do you want a pull-request, or are you happy for me to just apply?

[PATCH RESEND v6 6/6] mfd: axp20x: Enable AXP22X regulators

[Chen-Yu Tsai]

Now that the axp20x-regulators driver supports different variants of the
AXP family, we can enable regulator support for AXP22X without the risk
of incorrectly configuring regulators.
