commit bf5570590a981d0659d0808d2d4bcda21b27a2a5 upstream.
MIPS Malta platform code registers the PCI southbridge legacy port I/O
PS/2 keyboard range as a standard resource marked as busy. It prevents
the i8042 driver from registering as it fails to claim the resource in
a call to i8042_platform_init(). Consequently PS/2 keyboard and mouse
devices cannot be used with this platform.
Fix the issue by removing the busy marker from the standard reservation,
making the driver register successfully:
serio: i8042 KBD port at 0x60,0x64 irq 1
serio: i8042 AUX port at 0x60,0x64 irq 12
and the resource show up as expected among the legacy devices:
00000000-00ffffff : MSC PCI I/O
00000000-0000001f : dma1
00000020-00000021 : pic1
00000040-0000005f : timer
00000060-0000006f : keyboard
00000060-0000006f : i8042
00000070-00000077 : rtc0
00000080-0000008f : dma page reg
000000a0-000000a1 : pic2
000000c0-000000df : dma2
[...]
If the i8042 driver has not been configured, then the standard resource
will remain there preventing any conflicting dynamic assignment of this
PCI port I/O address range.

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.
