Subject: [PATCH v3 00/16] Add support for AXP192 PMIC

Changes in v3:

* Update pinctrl driver to address Andy Shevchenko's review comments
  from v1, and fix a few other issues.
* Add gpio-ranges property and example snippet to gpio DT bindings.
* Update commit message of patch 01/16 to point out that all register
  addresses are obtained using sub_irq_reg().
* Document ccc_table in axp20x_battery. Also update commit message to
  note a small fix that is part of that patch.
* Drop axp20x_adc consolidation patch in favor of using separate adc_raw
  functions. It's a minor code size optimization that may not be worth
  the effort due to implementation complexity.
* Use the FIELD_GET macro in axp20x_adc to further clarify intent.
* Fix a typo in the regulator driver where an AXP20X regulator ID was
  mistakenly used instead of an AXP192 regulator ID. Also carry over
  an Acked-by: tag from v1. Hope that's okay.
* Accumulate Acked-by: tags from v1 on DT patches.
* Accumulate Acked-by: tags from v2.

Note that regmap maintainer Mark Brown has said the first two patches to
regmap-irq aren't suitable for inclusion into the kernel in their current
state. I'm including them for v3 so the series remains testable.

Changes in v2:

* Do a little cleanup of axp20x_adc suggested by Jonathan Cameron
* Consolidate ADC read functions in axp20x_adc
* Drop the axp192's read_label callback in axp20x_adc
* Clean up the axp192-gpio dt bindings
* Rewrite a problematic bit of code in axp20x_usb_power reported
  by kernel test robot
* Support AXP192 in axp20x_battery
* Split up regmap-irq changes to two separate patches

Cover letter from v1:

Hi all,

This patch series adds support for the X-Powers AXP192 PMIC to the
AXP20x driver framework.

The first patch is a small change to regmap-irq to support the AXP192's
unusual IRQ register layout. It isn't possible to include all of the
IRQ registers in one regmap-irq chip without this.

The rest of the changes are pretty straightforward, I think the only
notable parts are the axp20x_adc driver where there seems to be some
opportunities for code reuse (the axp192 is nearly a duplicate of the
axp20x) and the addition of a new pinctrl driver for the axp192, since
the axp20x pinctrl driver was not very easy to adapt.
