Some interrupt controllers use separate bits for controlling rising and falling edge interrupts in the mask register i.e. they have one interrupt for rising edge and one for falling. We already handle the case where we have a single interrupt in the mask register and a separate type configuration register. Add a new switch to regmap_irq_chip which tells the framework to use the mask_base address for configuring the edge of the interrupts that define type_falling/rising_mask values. For such interrupts we never update the type_base bits. For interrupts that don't define type masks or their regmap irq chip doesn't set the type_in_mask to true everything stays the same.

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.
