where the SoC is not powered by the PMIC or has a short time backup
energy to handle shutdown of critical hardware. In that case it may be
useful to connect the errb and handle errb events.

System controller node represents a register region containing a set
of miscellaneous registers. The registers are not cohesive enough to
represent as any specific type of device. The typical use-case is
for some other node's driver, or platform-specific code, to acquire
a reference to the syscon node (e.g. by phandle, node path, or
search using a specific compatible value), interrogate the node (or
associated OS driver) to determine the location of the registers,
and access the registers directly.

/*
* Copyright (C) 2024 ROHM Semiconductors
*
* ROHM BD96801 PMIC driver
*
* This version of the "BD86801 scalable PMIC"'s driver supports only very
* basic set of the PMIC features. Most notably, there is no support for
* the ERRB interrupt and the configurations which should be done when the
* PMIC is in STBY mode.
*
* Supporting the ERRB interrupt would require dropping the regmap-IRQ
* usage or working around (or accepting a presense of) a naming conflict
* in debugFS IRQs.
*
* Being able to reliably do the configurations like changing the
* regulator safety limits (like limits for the over/under -voltages, over
* current, thermal protection) would require the configuring driver to be
* synchronized with entity causing the PMIC state transitions. Eg, one
* should be able to ensure the PMIC is in STBY state when the
* configurations are applied to the hardware. How and when the PMIC state
* transitions are to be done is likely to be very system specific, as will
* be the need to configure these safety limits. Hence it's not simple to
* come up with a generic solution.
*
* Users who require the ERRB handling and STBY state configurations can
* have a look at the original RFC:
* https://lore.kernel.org/all/cover.1712920132.git.mazziesaccount@gmail.com/
* which implements a workaround to debugFS naming conflict and some of
* the safety limit configurations - but leaves the state change handling
* and synchronization to be implemented.
*
* It would be great to hear (and receive a patch!) if you implement the
* STBY configuration support or a proper fix to the debugFS naming
* conflict in your downstream driver ;)
