mainlining shenanigans
f8410e6265
Compiling an irqchip driver as a platform driver needs to bunch of
things to be done right:
- Making sure the parent domain is initialized first
- Making sure the device can't be unbound from sysfs
- Disallowing module unload if it's built as a module
- Finding the parent node
- Etc.
Instead of trying to make sure all future irqchip platform drivers get
this right, provide boilerplate macros that take care of all of this.
An example use would look something like this. Where acme_foo_init and
acme_bar_init are similar to what would be passed to IRQCHIP_DECLARE.
IRQCHIP_PLATFORM_DRIVER_BEGIN(acme_irq)
IRQCHIP_MATCH("acme,foo", acme_foo_init)
IRQCHIP_MATCH("acme,bar", acme_bar_init)
IRQCHIP_PLATFORM_DRIVER_END(acme_irq)

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.
