Subject: [PATCH v4 0/6] Support ROHM BD96801 Scalable PMIC
Support ROHM BD96801 Scalable PMIC
The ROHM BD96801 is automotive grade PMIC, intended to be usable in
multiple solutions. The BD96801 can be used as a stand-alone, or together
with separate 'companion PMICs'. This modular approach aims to make this
PMIC suitable for various use-cases.
This series brings only limited support. The more complete set of
features was sent in the RFC:
https://lore.kernel.org/lkml/cover.1712058690.git.mazziesaccount@gmail.com/
The v3: implemented also support for ERRB interrupt and setting a name
suffix to IRQ domains. That work was postponed and will be continued
after some unrelated changes to irqdomain code are completed as
discussed here:
https://lore.kernel.org/all/87plst28yk.ffs@tglx/
Revision history still tries to summarize changes from the RFC for the
reviewers.
Revision history:
v3 => v4:
- Drop patches 7 to 10 (inclusive) until preparatory irqdomain changes
are done.
- Cleanups as suggested by Lee.
- Change the regulator subdevice name. (MFD and regulators).
- Minor styling in MFD driver
v2 => v3: Mostly based on feedback from Thomas Gleixner
- Added acks from Krzysztof and Mark
- Rebased on v6.10-rc2
- Drop name suffix support for legacy IRQ domains (both
irqdomain and regmap)
- Improve the commit message for patch 7/10
v1 => v2:
- Add support for setting a name suffix for fwnode backed IRQ domains.
- Add support for setting a domain name suffix for regmap-IRQ.
- Add handling of ERRB IRQs.
- Small fixes based on feedback.
RFCv2 => v1:
- Drop ERRB IRQ from drivers (but not DT bindings).
- Drop configuration which requires STBY - state.
- Fix the register lock race by moving it from the regulator
driver to the MFD driver.
RFCv1 => RFCv2:
- Tidying code based on feedback form Krzysztof Kozlowski and
Lee Jones.
- Documented undocumented watchdog related DT properties.
- Added usage of the watchdog IRQ.
- Use irq_domain_update_bus_token() to work-around debugFS name
collision for IRQ domains.
