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 since v4 has 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.
Revision history:
v5 => v6:
- MFD fixes as suggested by Lee
- Styling mostly
- New patch to Fix comment style for MFD driver
More accurate changelog in individual patches
v4 => v5:
- dt-binding fixes as discussed in v4 reviews.
- Drop rohm,vdr-battery.yaml and add vdr properties to battery.yaml
- Drop 'rohm,' -vendor-prefix from vdr properties
- Link to v4:

More accurate changelog in individual patches
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.
