Add support for more interrupt controllers by switching from of_irq_init() to irqchip_init() in Lantiq's arch_init_irq(). This requires switching the ICU interrupt controller to use IRQCHIP_DECLARE(), like a real irqchip driver would do. This is needed for future changes when new irqchip drivers are implemented: - a dedicated driver for the EIU interrupt controller - a driver for the MSI PIC (Programmable Interrupt Controller) found on VRX200 and newer SoCs - ..or any other driver which uses IRQCHIP_DECLARE Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
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.
