[PATCH v2 0/8] regulator: axp20x: Stop AXP209 from crashing when enabling LDO3

[Priit Laes]

This is a second edition of a series that implements voltage
ramping for AXP209 DCDC2 and LDO3 regulators and software
based soft-start for AXP209 LDO3 regulator.

Both features are needed to work around a PMIC shutdown when
toggling LDO3 on certain boards with high capacitance on the
LDO3 output.

Similar features (or workarounds) have been also implemented
on u-boot side [1].

Changes since v1:
- Rebased on top of next and dropped already merged patches.
- Dropped LDO4 full range devicetree change for Lime2 (prev patch 9)
  in favor of general pin-bank regulator dependency [2].
- Fixed paths in devicetree bindings (patch 3)
- Added note about software based soft-start for LDO3 (patch 5)
