Masahiro Yamada bbfbf04c2d gpio: uniphier: set legitimate irq trigger type in .to_irq hook
If a GPIO chip is a part of a hierarchy IRQ domain, there is no
way to specify the trigger type when gpio(d)_to_irq() allocates an
interrupt on-the-fly.

Currently, uniphier_gpio_to_irq() sets IRQ_TYPE_NONE, but it causes
an error in the .alloc() hook of the parent domain.
(drivers/irq/irq-uniphier-aidet.c)

Even if we change irq-uniphier-aidet.c to accept the NONE type,
GIC complains about it since commit 83a86fbb5b ("irqchip/gic:
Loudly complain about the use of IRQ_TYPE_NONE").

Instead, use IRQ_TYPE_LEVEL_HIGH as a temporary value when an irq
is allocated.  irq_set_irq_type() will override it when the irq is
really requested.

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
