The current unbinding process for Madera has some issues. The trouble is runtime PM is disabled as the first step of the process, but some of the drivers release IRQs causing regmap IRQ to issue a runtime get which fails. To allow runtime PM to remain enabled during mfd_remove_devices, the DCVDD regulator must remain available. In the case of external DCVDD's this is simple, the regulator can simply be disabled/put after the call to mfd_remove_devices. However, in the case of an internally supplied DCVDD the regulator needs to be released after the other MFD children depending on it. Use the new MFD mfd_remove_devices_late functionality to split the DCVDD regulator off from the other drivers.

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.
