[PATCH v12 0/6] Add battery charger driver support for MP2629

From: Saravanan Sekar
Date: Tue May 26 2020 - 05:07:10 EST

changes in v12:
- added SOB Acked-for-MFD-by: Lee Jones <lee.jones@xxxxxxxxxx>

changes in v11:
- module_remove part replaced by devm_add_action_or_reset in charger patch
- minor review comments solved in mfd and adc patch

I expect, that Lee will provide an immutable branch for me and
Jonathan once the MFD bits have been reviewed. Please tell me,
if I should prepare one instead.

changes in v10:
- fixed typo, \n in dev_err
- dt bindings Warning (unit_address_vs_reg) reported by bot

changes in v9:
- fixed review comments in mp2629 power supply such as resource based
iio channel, replace workqueue by threaded irq, irq get with "_optional"

changes in v8:
- fixed order of call in probe/remove in iio adc
