Subject[PATCH v4 00/15] Add support for AXP192 PMIC
Date
Changes in v4:

* Drop regmap-irq patches and rebase on top of the regmap-irq
refactoring series[1], which implements the same functionality.
* Reorder mfd_cells, putting one-line entries at the bottom.
* Fix incorrect example in axp192-gpio device tree bindings.
* Perform adc_en2 flag -> adc_en2_mask conversion in axp20x_adc
as a separate patch.
* Simplify axp192_usb_power_set_current_max().
* Drop unneeded OF dependency in pin control driver, and document
tables used for describing register layouts.
* Various style fixups suggested by Andy Shevchenko.

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.
