Tony Lindgren ac89473213 mfd: cpcap: Fix interrupt to use level interrupt
I made a mistake assuming the device tree configuration for interrupt
triggering was somehow passed to the SPI device but it's not.

In the Motorola Linux kernel tree CPCAP PMIC is configured as a rising
edge triggered interrupt, but then then it's interrupt handler keeps
looping until the GPIO line goes down. So the CPCAP interrupt is clearly
a level interrupt and not an edge interrupt.

Earlier when I tried to configure it as level interrupt using the
device tree, I did not account that the triggering only gets passed
to the SPI core and it also needs to be specified in the CPCAP driver
when we do devm_regmap_add_irq_chip().

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
