Merge series from Matti Vaittinen <mazziesaccount@gmail.com>: Devices can provide multiple interrupt lines. One reason for this is that a device has multiple subfunctions, each providing its own interrupt line. Another reason is that a device can be designed to be used (also) on a system where some of the interrupts can be routed to another processor. A line often further acts as a demultiplex for specific interrupts and has it's respective set of interrupt (status, mask, ack, ...) registers. Regmap supports the handling of these registers and demultiplexing interrupts, but interrupt domain code ends up assigning the same name for the per interrupt line domains This series adds possibility for giving a name suffix for an interrupt Previous discussion can be found from: https://lore.kernel.org/all/87plst28yk.ffs@tglx/ https://lore.kernel.org/all/15685ef6-92a5-41df-9148-1a67ceaec47b@gmail.com/ The domain suffix support added in this series will be used by the ROHM BD96801 ERRB IRQ support code. The BD96801 ERRB support will need the initial BD96801 driver code, which is not yet in irq/core or regmap trees. Thus the user for this new support is not included in the series, but will be sent once the name suffix support gets merged.
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 reStructuredText 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.
