Subject: [PATCH v3 00/16] Support ROHM BD72720 PMIC

The ROHM BD72720 is a new power management IC for portable, battery
powered devices. It integrates 10 BUCKs and 11 LDOs, RTC, charger, LEDs,
GPIOs and a clock gate. To me the BD72720 seems like a successor to the
BD71828 and BD71815 PMICs.

This series depends on
5bff79dad20a ("power: supply: Add bd718(15/28/78) charger driver")
which is in power-supply tree, for-next. Thus, the series is based on
it.

Revision history:
  v2 => v3:
  - rebased to power-supply/for-next as dependencies are merged to there
  - plenty of dt-binding changes as suggested by reviewers
  - add new patch to better document existing 'trickle-charging' property
  More accurate changelog in individual patches

  RFCv1 => v2:
  - Drop RFC status
  - Use stacked regmaps to hide secondary map from the sub-drivers
  - Quite a few styling fixes and improvements as suggested by
    reviewers. More accurate changelog in individual patches.
  - Link to v1:
    https://lore.kernel.org/all/cover.1759824376.git.mazziesaccount@gmail.com/

It may be worth nothing that the 'From' header changed as I send these
now via linux.dev mail, because gmail started filtering some of the
outgoing patch mails. Commits should still be from "Matti Vaittinen
<mazziesaccount@...il.com>", which should be handed by in-(mail)-body
From -line. Please, let me know if I messed it up.
