[PATCH v4 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.

The testing of v4 suffered some hardware-issues after I accidentally
enabled charging while the PMIC's battery pin was connected to the I/O
domain. Some heat was generated, not terribly lot smoke though...

After the incident I've had occasional I2C failures. I, however, suspect
the root cause is HW damage in I/O lines since changes in this revision
have been made to dt-bindings. It's still fair to note that though, as
my testing was impacted.

Revision history:
  v3 => v4:
  - dt-binding fixes to the BD72720 MFD example and regulator bindings
  More accurate changelog in individual patches

  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:
