[PATCH 0/2] ROHM BD96801 Support ERRB IRQ

[Matti Vaittinen <mazziesaccount@gmail.com>]

Add ERRB IRQ support to ROHM BD96801 PMIC driver.

The BD96801 has two IRQ pins, ERRB and INTB. ERRB is used to notify
'fatal' events so handling it has not been mandatory. However, there
are use-cases where handling the ERRB interrupts may be beneficial.

---

Supporting more than one IRQ pin in one device, using the regmap-IRQ,
caused an IRQ domain naming collision in the debugFS when device-tree
was used.

In order to avoid the collision, support for adding a name suffix to
IRQ domain was merged in regmap tree at
commit c69bb91c47e8 ("regmap IRQ support for devices with multiple IRQs")
This is required for the MFD driver to compile. Hence this series is
based on the regmap/for-6.12.

Furthermore, there has been a few (trivial) fixes to the BD96801 driver
in the regulator tree, and thus merge conflicts are possible. I can
re-spin the regulator driver based on the regulator tree when there is
a branch with the required IRQ domain and regmap commits as well as the
MFD driver. The MFD driver with ERRB support is needed so that the
regulator probe won't break for the users with the "errb" in
device-tree.

The ERRB patches were originally part of this series:
https://lore.kernel.org/all/cover.1717486682.git.mazziesaccount@gmail.com/

Revision history in the patches refers to the old versions in that
series.
