Pali Rohár f1de50e1db gpio: mpc8xxx: Fix support for IRQ_TYPE_LEVEL_LOW flow_type in mpc85xx
[ Upstream commit 279c12df8d2efb28def9d037f288cbfb97c30fe2 ]

Commit e39d5ef678 ("powerpc/5xxx: extend mpc8xxx_gpio driver to support
mpc512x gpios") implemented support for IRQ_TYPE_LEVEL_LOW flow type in
mpc512x via falling edge type. Do same for mpc85xx which support was added
in commit 345e5c8a1c ("powerpc: Add interrupt support to mpc8xxx_gpio").

Fixes probing of lm90 hwmon driver on mpc85xx based board which use level
interrupt. Without it kernel prints error and refuse lm90 to work:

    [   15.258370] genirq: Setting trigger mode 8 for irq 49 failed (mpc8xxx_irq_set_type+0x0/0xf8)
    [   15.267168] lm90 0-004c: cannot request IRQ 49
    [   15.272708] lm90: probe of 0-004c failed with error -22

Fixes: 345e5c8a1c ("powerpc: Add interrupt support to mpc8xxx_gpio")

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.
