[PATCH v4 0/7] mfd: axp20x: add AXP221 PMIC support

[Boris BREZILLON]

Hello,

This patch series adds basic support for X-Powers' AXP221 PMIC.

At the moment the MFD device only exposes AXP221 regulators but other
subdevices might be added later.

Best Regards,

Boris

Changes since v3:
 - rework mfd probe to avoid multiple AXP variant tests
 - add new compatible string to the DT bindings doc

Changes since v2:
 - add helper functions for regulator set registration
 - fix a copy/paste error in the axp20x mfd driver

Changes since v1:
 - merge code with the axp20x driver
