[PATCH v2 0/4] Initial support for XPowers AXP288 PMIC

[Jacob Pan]

XPowers AXP288 is a customized PMIC found on some Intel Baytrail-CR platforms.
It comes with sub-functions such as USB charging, fuel gauge, ADC, and many LDO
and BUCK channels.

By extending the existing AXP20x driver, this patchset adds basic support
for AXP288 PMIC with GPADC as one MFD cell device driver. It also adds hooks
for ACPI opregion handler driver which can be used to handle ACPI requests.

Currently, the PMIC driver in this patchset does not support platform data
enumeration. But when ACPI _DSD and unified device properties become available,
cell devices with platform data will be added.

This patch does not use intel_soc_pmic core for i2c and regmap handling in that
axp288 shares similar programming interface with other Xpower PMICs supported in
axp20x.c. Therefore, extending axp20x.c to include axp288 makes more sense.

Changes v2:
	- use format -M for 1/4
	- minor tweak based on Maxime's review

Jacob Pan (4):
  mfd/axp20x: rename files to support more devices
  mfd/axp2xx: extend axp20x to support axp288 pmic
  regulator/axp20x: use axp2xx consolidated header
  iio/adc/axp288: add support for axp288 gpadc
