Subject: [PATCH v1 0/6] Support ROHM BD96801 scalable PMIC
Date: Tue, 30 Apr 2024 14:59:18 +0300 [thread overview]
Message-ID: <cover.1714478142.git.mazziesaccount@gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 3422 bytes --]
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/
As writing of this there is no known system using the ERRB interrupts,
or doing configurations which require the PMIC to be in STBY state using
Linux driver. Hence it felt natural to upstream only partial support for
now, while leaving a note about the RFC series with more complete
support for those who may need it later.
Revision history still tries to summarize changes from the RFC for the
reviewers.
Revision history:
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.
- Fix watchdog timeout handling
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.
