Subject: [PATCH v5 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:
v4 => v5:
	- Drop unintended Makefile change from regulator Makefile

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.
