At the moment we allow the AXP15060 and the AXP806 PMICs to omit the interrupt line to the SoC, and we skip registering the PEK (power key) driver in this case, since that crashes when no IRQ is described in the DT node. The IRQ pin potentially not being connected to anything does affect more PMICs, though, and the PEK driver is not the only one requiring an interrupt: at least the AC power supply driver crashes in a similar fashion. Generalise the handling of AXP MFD devices when the platform tables describe no interrupt, by allowing each device to specify an alternative MFD list for this case. If no specific alternative is specified, we go with the safe default of "just the regulators", which matches the current situation. This enables new devices using the AXP313a PMIC, but not connecting the IRQ pin.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
