Jianmin Lv 7f4f66ac83 irqchip/loongson-liointc: Fix IRQ trigger polarity 
commit 1d7471b4e0 upstream.

For the INT_POLARITY register of Loongson-2K series IRQ
controller, '0' indicates high level or rising edge triggered,
'1' indicates low level or falling edge triggered, and we
can find out the information from the Loongson 2K1000LA User
Manual v1.0, Table 9-2, Section 9.3 (中断寄存器描述 / Description
of the Interrupt Registers).

For Loongson-3 CPU series, setting INT_POLARITY register is not
supported and writting it has no effect.

So trigger polarity setting shouled be fixed for Loongson-2K CPU
series.

Fixes: 17343d0b40 ("irqchip/loongson-liointc: Support to set IRQ type for ACPI path")

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.

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.
