Subject: [PATCH v6 00/17] Support ROHM BD72720 PMIC
Date: Thu, 27 Nov 2025 13:16:26 +0200	[thread overview]
Message-ID: <cover.1764241265.git.mazziesaccount@gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 4384 bytes --]

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:
    https://lore.kernel.org/all/cover.1763022807.git.mazziesaccount@gmail.com/
  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.
  - Link to v1:
    https://lore.kernel.org/all/cover.1759824376.git.mazziesaccount@gmail.com/
